JiuVPN User Guide

Understanding international connections and service boundaries

First, understand the difference between your account, subscription, and app

JiuVPN is a subscription service for international connectivity, with 100+ countries / 160+ routes. It supports Windows / macOS / iOS / Android / Linux, with unlimited devices online at the same time. Your account stores orders and service status, your subscription delivers available routes to the app, and the app establishes a connection on your device. These parts work together, but they are not interchangeable. Being able to sign in to the website only means the account portal is accessible. Installing the app does not mean your subscription is active or a route is connected.

Think of the process as getting access to the service, sending the connection configuration to your device, and then choosing a suitable route. The plan status in your account answers “Can I use the service right now?” The app configuration answers “How is this device set up to connect?” Only the result in your browser or app tells you whether the target service is working. Checking in this order is more effective than repeatedly reinstalling the app. The following chapters use the same sequence: verify each stage before moving on.

A route’s region is not your device’s location

The region in a route name usually helps identify its exit location or route group; it does not mean your device has physically moved there. An app may also consider your account region, billing details, location permissions, and activity history, so a route name alone cannot tell you whether a feature will be available. Follow local laws and the target platform’s terms when accessing websites. A network connection can improve the path to a service, but it does not grant account eligibility or change the rules you have agreed to.

IEPL, relay, and direct routes describe different ways a connection is organized. Dedicated lines focus on route planning, relays connect through intermediate nodes, and direct routes use the corresponding direct path. The name alone does not rank real-world performance. Your local network, carrier routing, the target website’s response, and the time of day can all affect the result. If you’re new to the service, start with a route suitable for your target region and test it with the same app task. You don’t need to learn every technical term first.

Connection protection and app permissions have different roles

JiuVPN’s trust information includes quantum encryption. You should still make informed choices about device security, account passwords, and app permissions. A connection service cannot replace system updates or stop you from voluntarily sharing sensitive information with an untrusted website. Check the domain before signing in, and stop entering information if your browser shows a certificate warning. When using a shared device, sign out when you’re done and check downloads, the clipboard, and saved browser data so configuration or sign-in details aren’t left behind.

Set up a clear starting point

Before you start, confirm that your device can access ordinary websites, its system clock is correct, and no other proxy app is controlling the network. If your basic connection is already having problems, fix the local network first; otherwise, it will be difficult to identify the cause after importing your subscription. Choose a configuration name you can recognize and decide which everyday device to test first. Although there is no device limit, configuring devices one at a time makes it easier to tell which step caused an issue.

If the app uses terms such as “nodes,” “rules,” or “global mode,” start with VPN terminology for beginners, then return to this chapter. You don’t need to understand protocol details before using the service; each step has an observable sign of success. By the end of this chapter, you should understand how your account, subscription, and app relate, and know to verify your local network, route, and target app separately rather than treating every issue as the same connection problem.

Choose a monthly plan or a data package

Consider how often you’ll use the service, then compare data allowances

Monthly plans suit regular use, with data resetting each month on the activation date. Options are ¥9.9/month with 60GB, ¥18/month with 250GB, and ¥28/month with 500GB. Think about your main activities: text searches, document collaboration, streaming video, and syncing large files use different amounts of data. Don’t choose based only on the number of devices. There’s no device limit, so what matters is their combined data use and whether they’re active at the same time.

Data packages suit occasional use when you want to connect as needed and track your remaining balance. They’re used until depleted and never expire. Options are ¥158/300GB, ¥358/1000GB, and ¥658/3000GB. The key difference from a monthly plan is how long the data remains available, not how you use the app. Monthly reset rules don’t apply to data packages, and “never expires” doesn’t mean websites, devices, or network conditions will never change.

Consider data needs separately from connection quality

A larger data allowance provides more data; it doesn’t mean a particular website will load faster. If meetings keep breaking up or pages time out occasionally, check your route and local network instead of treating an upgrade as a troubleshooting fix. Conversely, if your account shows that you’re low on data, switching routes repeatedly won’t solve the allowance issue. First determine whether the problem is “poor connection quality” or “service status doesn’t meet the requirements for use” to avoid unnecessary steps.

There’s no need to rely on unverified data-use estimates. Check your remaining balance in the account portal, use the service as you normally would for a while, then check the change. Background sync, app updates, and other online devices may also use data, so check whether large transfers are running. Apps differ in video quality, caching, and upload activity. Don’t treat one session as a universal benchmark or estimate total usage from time spent on a webpage.

Understand resets, upgrades, and payment

Monthly data resets each month on your activation date; don’t assume it resets at the start of the calendar month. Check the current billing period and reset information in the account portal. If you upgrade mid-cycle, the price difference is prorated by the remaining days. Review the order details shown before confirming; don’t estimate the amount due or remaining term by subtracting full-month prices yourself. This guide does not add unlisted annual or quarterly plans, discounts, or stacking rules. Check the current order details if you have questions about changing plans.

JiuVPN accepts Alipay / WeChat Pay / USDT and offers a 7-day no-questions-asked refund. Payment methods are for completing an order, not for deciding which plan suits you. Before choosing, review all prices and terms on the plans page, then read the refund policy for the application process. A refund policy is no substitute for checking service coverage, data rules, and device compatibility before you proceed.

Keep a clear record of why you chose your plan

Once you’ve chosen, note the plan type, data allowance, and reason for your choice. There’s no need to store payment credentials in a publicly accessible place. If you use the service regularly, check whether your remaining monthly data matches your typical usage. If you use it occasionally, keep an eye on your data package balance. If your needs change from reading to frequent video or remote syncing, reassess your actual usage rather than relying on old habits. Success isn’t choosing the largest plan; it’s knowing when your data resets, how you use it, and how to adjust based on your account history.

Set up your account and confirm your order

Use account details you can store securely

JiuVPN does not require an email address. Create an account with a username and password on the account setup page. Follow the field prompts and check your input method, capitalization, and spaces before submitting. Choose a username you can recognize and a password you don’t use on other websites. Don’t use the same text for both, or post your full account details in a public forum and ask someone else to check whether they work.

Since no email address is required, you can’t rely on the account recovery methods you may use on other websites. After creating your account, store your details in a password manager you control or another secure place. Use the recovery options actually shown in the account portal; this guide does not promise recovery methods that aren’t listed there. If you set up your account on a shared computer, check whether the browser saved your password. If you don’t control the device long-term, sign out and remove unnecessary account data.

Confirm your plan in the same account

Sign in and open the plans dashboard. Double-check the plan name, whether it’s a monthly plan or data package, the price, and the data allowance against your choice in the previous chapter. Don’t rely on button color or page position to tell which option is selected. If you’ve switched browsers or devices, confirm which account is signed in before paying. Otherwise, you may place an order in a different account and then look for the subscription in the original one, thinking it hasn’t arrived.

After an order is created, the payment page may redirect you to the selected provider. Check the order details before leaving the account portal. Once payment is complete, return to the same account and check its status. Alipay / WeChat Pay / USDT are supported payment methods; follow the instructions shown on the order page. For USDT, carefully verify the network, recipient details, and amount shown at checkout. Don’t substitute details based on an earlier transaction or reuse payment information from an old order.

Confirm payment by checking the order status

A payment provider showing “complete” and your account portal confirming the order are related but separate steps. After returning, check your order history and account overview to confirm the plan status has updated, then get your subscription. If the page still shows the old status, refresh it and reopen the overview while keeping your order information. Don’t create duplicate orders just because the page hasn’t updated yet, and don’t treat a payment screenshot as proof that your app is ready to connect.

If payment is complete but the order still looks wrong, first check that you’re signed in to the correct account, have opened the right order, and the payment result matches this transaction. Note the order number, payment result, and current message in the account portal, then contact support through the support ticket portal. Describe what happened without guessing at the cause. Don’t include your full password, complete subscription link, or unrelated payment details, and don’t ask people to investigate on a public page.

Keep a clear record of what you’ve verified

At this stage, confirm that you can sign in, find the order under that account, and see a service status that matches your chosen plan. Keep notes only as long as you need to verify the details yourself; there’s no need to take a full-page screenshot containing sensitive information. If you need a screenshot to explain a problem, hide anything unnecessary beyond your username, especially details in the browser address bar, QR codes, and pop-up windows that may contain personal configuration data. Information near the edge of a screenshot can still include complete access credentials.

When renewing, changing your plan, or requesting a refund, check your records in the same account first. For the 7-day no-questions-asked refund process, see the refund policy. Don’t assume how long a payment provider will take to process a refund or make it available. Once this chapter is complete, move on to getting your subscription: the account setup is ready when you can see the correct plan status. If it’s still unclear, stop and verify it first rather than installing more apps to work around an account issue.

Get your subscription and manage its configuration

A subscription link is a configuration credential, not an ordinary bookmark

After confirming your account and order, open the account overview and follow the subscription instructions shown there. The subscription link lets an app retrieve route configuration and may contain access credentials tied to your account, so protect it like a password. It isn’t a product page to share with friends, and shouldn’t be pasted into public forums, online conversion tools, or screenshots. When describing a problem, share the app’s message and the steps you took instead.

Depending on the account portal and platform, you may be asked to copy a link or send it directly to the app. After copying it, make sure you paste it into the app’s subscription or remote configuration field, not a regular browser address bar. If opening the link in a browser displays text, a download prompt, or another response, that alone doesn’t tell you whether the subscription works. The reliable check is to import it into a compatible app and confirm that it recognizes the configuration and lists available routes.

Check the link and configuration type before importing

When pasting from the clipboard, check for extra quotation marks, line breaks, or explanatory text. Some chat apps wrap long links over multiple lines, and manually joining them can omit characters. Whenever possible, copy directly from your own account portal. If the app says the address is invalid, clear the field and copy it again. Don’t edit the link parameters. Subscription formats also need to match the app; don’t rename a configuration intended for another program and assume it will work.

Give the imported configuration a name you’ll recognize, such as “JiuVPN everyday connection.” Use the name only to distinguish your own configurations; don’t include account details. If your device already has other configurations, keep them for now and make sure you know which one is selected. You can tidy things up after verifying the new one. That way, if the new configuration won’t update, you’ll know which step caused the problem instead of losing your point of comparison by clearing everything.

Know the difference between updating a configuration and connecting

Updating a subscription retrieves route and rule configuration again; the connection switch starts or stops the device’s connection using the current configuration. A successful update doesn’t mean you’re connected, and being connected doesn’t mean the configuration is up to date. If the route list is empty, names don’t match the account portal, or the configuration won’t load, check the subscription update first. If traffic isn’t taking the expected path, check the selected configuration, route, and connection status rather than repeatedly clicking update.

If an update fails, note the exact message from the app. An invalid address, a local network that can’t reach the subscription endpoint, an account that isn’t eligible for use, and an incompatible configuration format require different fixes. First check your basic network and account status, then try copying the link again. Don’t give your real link to a third-party “subscription checker”; it may give them access to your configuration. If you need help, describe the error in an account support ticket without sharing credentials.

Use a separate, traceable configuration on each device

There’s no device limit, but each device still needs its own app installation, subscription import, and connection check. A successful import on your computer won’t automatically configure your other devices. You can securely transfer your subscription between devices you control, but consider who can access clipboard sync, cloud notes, and shared photo albums. If you’ve exposed the full subscription to someone untrusted, check whether the account portal offers a reset option. If it does, reset it and update the saved configuration on each device.

If the account portal doesn’t show a clear reset or management option, don’t guess at an endpoint or edit the address. Contact support instead. When retiring an old device, check both the app configuration and any saved copies of the link; uninstalling the app alone may leave access details behind. For guidance on account creation, payment, and data retention, see Choosing a privacy-focused VPN and minimizing personal data. You’re done with this chapter when a compatible app recognizes the subscription and you know how to update and protect it.

Import the client on each platform

One download portal, with platform-specific steps

Get the app and platform instructions from the download section of the account portal. Sign in to download on Windows / Android / macOS / Linux. An active plan is required for the iOS link. You must be signed in to get your subscription. Don’t download apps from search results with similar names or try to open an installer for another platform. App interfaces vary by operating system and client; the steps below cover the same essentials: get the configuration, select it, and approve the connection.

Windows: Import first, then choose how to connect

Get the client for your device from the account portal, install it according to the instructions, and open it. Find the subscription, configuration, or import option. Paste your subscription, wait for the route list to load, and select the configuration. Start with the connection method recommended by the app, and watch for any system permission prompts. A system proxy usually affects apps that follow the system proxy settings, while tunnel mode may require additional permissions. They aren’t simply two names for the same switch.

If websites work but a desktop app doesn’t, first check whether it follows the system proxy settings. Then consider another supported traffic-routing method if needed. Don’t start by enabling several proxy apps at once. If regular websites stop working after you quit the app, reopen it and check whether the system proxy still points to a local endpoint that is no longer running.

macOS: Check system permissions separately from configuration import

Download the client from the account portal and install it as prompted by the system. Verify the app’s source before granting the requested permissions. Open the app, import your subscription, check the selected configuration and route, then allow it to establish a network connection. If a security alert appears, verify the download source and account portal instructions instead of disabling system security features altogether. Organization-managed devices may restrict network extensions or proxy changes; follow your device management requirements.

After importing, check separately that the connection is on. If your browser works but a developer tool doesn’t, check the tool’s own proxy settings and environment variables instead of assuming there’s a system connection problem. If switching networks interrupts access, stop and reconnect while keeping the existing subscription configuration. You don’t need to reinstall the app each time.

iOS: Installing the app doesn’t finish network setup

With an active plan, get the iOS download link from the account portal and install the app as instructed. After installation, return to the portal to get your subscription and import it into the compatible app. When iOS asks to add a network configuration, confirm that the request comes from the app you just installed and intend to use. Approve it, select the correct configuration and route, then connect. Seeing the app icon on your home screen doesn’t mean setup is complete.

If the account portal doesn’t show a download link, first check that you’re signed in to the right account and that your plan is active. While connecting, check whether another network configuration is already enabled. If an app can’t access a service, test it separately from your browser so you don’t mistake an account region requirement or app cache for an import issue.

Android: Check permissions and background behavior

Sign in and download the client from the account portal. Before installing, confirm that the file came from the current portal. Open the app, import your subscription, wait for it to load, and select a route. Then approve the connection request from Android. The permission dialog is part of establishing a connection; importing a configuration won’t bypass it. If the import fails, check the error message instead of repeatedly granting unrelated permissions.

If the connection fails after the screen turns off, check Android’s background operation and battery management settings for the client. Adjust only what’s needed; there’s no need to remove all restrictions from other apps. Verify the connection again after switching between Wi-Fi and mobile data. If another app on the device also controls network traffic, identify which app is currently handling it to avoid conflicting connection states.

Linux: Check which traffic the proxy covers

Sign in to the account portal to get the client, then install it according to the instructions for your distribution and desktop environment. After importing your subscription, choose a configuration and route in the app before confirming the connection mode. If system permission is required, review what it allows before proceeding. Don’t copy privilege-escalation commands from untrusted websites. Desktop proxy settings, terminal environment variables, and in-app proxies may each work independently. A working browser doesn’t mean every terminal task will use the same route.

If only terminal tasks are failing, check whether the current session has old proxy settings. If only desktop apps are affected, check their own settings. Verify the connection with your usual browser before adjusting other programs one at a time. You’re done with this chapter when the device has a recognizable configuration, you can select a route, and you’ve granted any required connection permissions—not merely when the app is installed.

Verify your connection and choose a route

Test with real tasks, not just the connection icon

An active connection indicator only tells you that the app has started working. You still need to confirm that your target app can complete a real task. First open an ordinary website you can usually access and check that your basic network is working. Then visit the international site you want to use and try a relevant task, such as opening a shared document, joining a meeting preview, or loading the content you need. Seeing a page title doesn’t mean all its resources have loaded, and opening a sign-in page doesn’t mean your account will meet the requirements for later features.

Keep the conditions as consistent as possible while testing: use the same device, network, and task. Check the current route first, then try another if needed. If you change the Wi-Fi network, browser, connection mode, and route all at once, you won’t know what made the difference. Keep the original configuration and note each change so you can reproduce the result instead of repeatedly resetting everything. If an issue is intermittent, check whether it only affects the target app before assuming the whole service is down; a single website may be undergoing maintenance.

Choose a region first, then consider the route type

Choose a region based on the target platform’s service area and account requirements, not simply because it’s closer. For ordinary websites and document collaboration, start with a region that meets your needs. For meetings and interactive apps, check audio continuity, video, and input response. For video, focus on consistent playback after it starts. Don’t compare different content in different regions and use the results to create a permanent route ranking.

Narrow down the cause based on the symptoms

If no websites open, stop the connection and check your basic network, then see whether the system proxy is still enabled. If ordinary websites work but the target site doesn’t, check the selected route, which rule matched, and the target platform’s status. If websites work but an app shows an error, check that app’s proxy settings, account eligibility, and cache. If only the subscription update fails, check the subscription portal and account status instead of changing connection settings on every device.

Handle certificate errors separately from ordinary timeouts. A certificate warning may be related to your system clock, the domain, or your network environment; don’t bypass the warning and enter your password. If a domain lookup fails, first check whether it affects just one website. Then check whether the client’s DNS handling matches the current connection mode. Don’t copy DNS addresses from untrusted sources, as that can make separate DNS and connection issues harder to distinguish.

Check account requirements separately for AI tools and streaming

AI tools may check your account region, eligibility, and session status. Streaming services may also show different results based on your account and content rights. If a message doesn’t change after switching routes, read the platform’s specific error instead of repeatedly changing your exit location. Changing your connection environment during a payment, account recovery, or important session may also trigger additional checks. For these scenarios, see the AI guide and streaming guide.

For more on regions and route types, see the servers and routes page. For remote meetings, see how to choose a route for remote work. You’re done with this chapter when your usual tasks work and you can tell whether an issue is with your basic network, account status, configuration, route, or target app. There’s no need to run lots of tests just to prove the connection works; your real workflow is usually the best measure of whether it suits your needs.

Data management, renewals, and refunds

Include account status in your routine checks

Once the service is working reliably, there’s no need to re-import your configuration every day. You should still know where to check your service status and remaining data. Open the account overview, confirm whether you’re using a monthly plan or a data package, and check its status. Monthly plan data resets each month on the activation date; data packages are used until depleted and never expire. A successful previous connection in the app doesn’t replace checking your current account status, especially after a plan change, low-data warning, or renewal.

When checking data use, consider all your devices together. There’s no limit on devices online at the same time, but each one doesn’t have its own separate data allowance. Background sync, system updates, video playback, and app activity on other devices can all affect the total. If usage looks different from what you expected, pause nonessential tasks, check each device’s network usage, and compare the account balance. Don’t assume there’s a billing issue based only on how long you used one app.

Keep a way to recover when updating the client

Updating the client and updating the subscription are different maintenance tasks. The first changes the app on your device; the second fetches the connection configuration again. Before updating the app, make sure you can still sign in to the account portal and note the configuration name and any essential settings. Don’t save your real subscription in a public note as a backup. Get the correct platform version from the portal’s download section and read the installation instructions first. If your device is managed by an organization, check that the update complies with its requirements before changing controlled network settings.

After updating, verify a familiar task before exploring new features. If a setting has been renamed, look for the equivalent by what it does rather than searching for an exact match with the old label. If something goes wrong, note what changed and the exact message; don’t guess at a version-related cause. This guide doesn’t list fixed app versions because the current instructions and platform requirements should come from the account portal. A static article can’t replace the download page.

Check your order again before renewing or changing plans

When you’re ready to continue, return to the plans dashboard to check the available options and your current status. Monthly plans are ¥9.9/month with 60GB, ¥18/month with 250GB, and ¥28/month with 500GB. Data packages are ¥158/300GB, ¥358/1000GB, and ¥658/3000GB. Choose based on your recent actual usage, not on worries about what you might need later. If your data allowance is sufficient but the connection is having problems, follow the connection checks in the earlier chapter instead of treating a renewal as a route fix.

If you upgrade mid-cycle, the price difference is prorated by the remaining days. Review the result shown in the account portal before submitting. Check the order confirmation to see how different orders affect your current service; don’t assume they’ll combine, extend, or replace one another. After paying, check your order history and account overview again to confirm the change matches what you expected. If you plan to use another device, first check whether its subscription needs updating instead of assuming every imported client will immediately receive new account information.

Keep refund requests separate from issue reports

JiuVPN offers a 7-day no-questions-asked refund. If you want to request one, read the refund policy, then use a support ticket in your current account to explain your request and identify the order. Don’t combine a connection issue and a refund request in a long message that makes it unclear what you need. If you need help with both, explain the outcome you’re seeking for each. This guide makes no additional promises about processing times, payment provider turnaround, or eligibility details not listed in the facts provided.

The most useful long-term records aren’t repeated speed tests. Note the routes you use, the modes that suit your needs, the last network environment where everything worked, and your plan status in the account portal. For more guidance, see what to look for when using a subscription over time. You’re done with this chapter when you can check data use, understand maintenance tasks, verify renewal details, and provide enough information to get help without exposing more than necessary.

Rule-based routing and advanced troubleshooting

Understand the modes before changing them

Rule mode typically uses matching conditions in the configuration to decide which path a request takes. Global mode sends requests within the client’s handling scope through the selected policy. “Global” is still subject to the client’s capabilities, system permissions, and app behavior; it doesn’t mean every activity on the device necessarily takes the same path. Start with the client’s recommended settings, then adjust for a specific need after your usual tasks work. Don’t turn on every option just because it’s available.

System proxy settings and tunnel routing are also different. A system proxy depends on whether apps follow the relevant settings. A tunnel may handle traffic through a virtual network interface and require additional permissions. If a tool ignores the system proxy, switching routes may not help. If the actual issue is a rule sending a domain directly, broadening the traffic scope may be more change than necessary. First confirm that the request reaches the client, then see which rule matched, and finally check the selected route.

Use logs to troubleshoot, but don’t expose credentials they contain

If the client provides connection records or logs, look at the entry for the operation that failed. Check the domain, matched rule, outbound selection, and error message. Close unrelated background requests and reproduce the task to make the relevant entry easier to find. Don’t post a full log publicly; it may include domains you’ve visited, account configuration, or other personal information. When submitting a support ticket, include only the relevant lines and check addresses, parameters, and file paths for sensitive details.

Use the structure below to record what happened, not what you think caused it. Describe the network as a home Wi-Fi connection or another type you can confirm, and use the route name shown in the app. Don’t add untested speed, latency, or packet-loss figures just to make the report look complete. If an error includes your subscription link, remove the credential portion and keep only the text that identifies the type of issue.

Platform: Windows
Symptom: The browser works, but the target desktop app cannot connect
Configuration: JiuVPN configuration selected; subscription update succeeded
Mode: Enter the mode name shown in the current client
Tried: Closed other proxy apps and reopened the target app
Error message: Paste the original text with sensitive information removed
Help needed: Check whether the app's proxy settings or rule matching need adjustment

Keep DNS, cache, and account status separate

DNS resolves a domain to an address needed for a connection; the route carries traffic afterward, and the target platform decides whether your account is eligible. A successful DNS lookup doesn’t mean the target app will allow your account to access it. A region message in the app doesn’t by itself indicate a DNS problem. Read the error type before changing settings, then check the corresponding client feature. If you need to change DNS behavior, save the original setting, change only what’s relevant, and verify whether to keep or restore it.

An app cache may retain an old session or details about the previous connection environment. Clearing it may also sign you out. Save important work first and follow the app’s own instructions; don’t clear all data by default. A browser’s private window can help distinguish some session-related factors, but it doesn’t prove the service offers a particular privacy guarantee or override the platform’s region and account rules. Use what you observe to narrow down the issue, not to draw unsupported conclusions.

Keep a way to undo your changes

Before adding custom rules, check whether the client supports local edits and whether subscription updates will overwrite them. Don’t change core settings generated from a subscription without recording the original values, and don’t paste large rule sets from untrusted sources. Note the purpose of each change, such as routing a work app the way you expect. Test the same task afterward and restore the original settings if it doesn’t help. Understanding the difference before and after a change is more useful for long-term maintenance than building a complicated configuration.

If only one device has a problem while another works on the same network, start by checking local permissions, leftover proxy settings, and app configuration. If multiple devices have the same issue on that network, compare the basic network and route status. If the connection works again after leaving the network, the difference in environment is worth investigating, but it doesn’t prove the specific cause. Use these comparisons to rule out one factor at a time instead of repeatedly trying random fixes.

You’ve now covered the complete process: your account status determines eligibility, your subscription provides configuration to the app, the app handles requests according to its permissions and rules, the route carries the connection, and the target platform determines available content and account features. For a simpler walkthrough, return to the quick start guide. For basic usage questions, see VPN FAQs for beginners. If you still can’t identify the issue, submit the smallest reproducible set of steps in an account support ticket instead of adding more settings you don’t understand.
