VPN Setup Guide

Understand your cross-border connection and subscription

Know the difference between your account, subscription, and client

Z3VPN provides a subscription service for cross-border connectivity. Your account lets you view plans, orders, and subscription details. A subscription provides the available routes and configuration to your client, which establishes the connection on your device. These parts work together, but they are not interchangeable. Signing in to the dashboard does not mean your device is connected, and installing a client does not mean it has a valid configuration. For your first setup, work through the steps in order: account, plan, subscription, client, and connection check. This helps avoid repeatedly changing settings before the information they depend on is in place.

The service covers 90+ countries and 240+ routes, with support for Windows / macOS / iOS / Android / Linux and unlimited simultaneous devices. Coverage indicates the available exit regions; it does not mean every destination offers the same content in every region. Unlimited devices also does not change how plan data is counted: devices on the same account share the plan’s resources. Each device does not have a separate allowance. Before setup, check which operating system you use, then get the appropriate client from the dashboard.

Understand the steps in a connection

A typical connection passes through your device, local network, selected route, and destination service. The client can change the connection path, but it cannot replace your local network or determine whether you meet a destination service’s account requirements. If your device is not connected to the internet, restore the basic connection first. If a service requires an account from a particular region, check its official rules. Keeping these boundaries clear helps identify where a problem occurs. Otherwise, account sign-in errors, content licensing restrictions, and network interruptions can all be mistaken for an unavailable route, leading troubleshooting in the wrong direction.

Regions in the route list indicate network exit locations; route types describe how the connection is structured. IEPL, relay, and direct routes can help guide your choice, but their labels do not guarantee how they will perform at a given moment. For meetings, browsing, and long video sessions, assess responsiveness, consistency, and buffering separately. Don’t base a long-term choice on a single speed test, and don’t assume a shorter geographic distance means a shorter overall route. See the global server locations page for the current list and guidance on choosing a route.

Build habits that make it easy to undo changes

Before changing settings, note your device’s operating system, current network, and the service you want to access. Then change one setting at a time and keep track of the original choice. If something changes, you’ll know whether it was due to the route, mode, or permissions. Client interfaces can vary by operating system and version, so this guide uses feature names such as “subscription,” “configuration,” and “connection” rather than relying on a button’s exact location. If you can’t find an option with the same name, check the current interface’s help first. Don’t delete a configuration or reset everything just because an option looks similar.

It’s also important to check the basic connection separately from the destination app. First, let the client load its configuration; then check its connection status; finally, open the app you want to use. Working backward from an app error can lead you to mistake an old session, cached data, or an app permission issue for a network problem. Keep a brief record of what you changed, what happened, and whether you could undo it. Don’t include passwords or subscription links. A record of the steps you took is enough to help with troubleshooting or support requests.

Choose a plan to match how you use it

Monthly plans vs. data packages

Start by considering how regularly you’ll use the service, then compare data allowances. A monthly plan suits regular use with a monthly allowance to manage. A data package suits occasional use when you want unused data to remain available. The key difference is how data is replenished and what happens to the remaining balance—not the product name. Monthly plan data resets each month on the activation date; data packages last until used and never expire. A monthly plan’s unused data does not keep accumulating, and a data package does not automatically refill each month.

The table below lists all prices and billing terms for easy comparison. First rule out the category that doesn’t fit your usage, then compare allowances within the right category. Don’t estimate your data needs based on someone else’s devices: browsing, meetings, file transfers, and video can use very different amounts. Start with usage records from your device or apps, if available. If a record only shows total network usage, remember it may include local updates and other activity that doesn’t go through the client, so it may not match your plan usage.

What else should you check besides data allowance?

All plans support unlimited devices, accept Alipay / WeChat Pay / USDT, and include a 60-day money-back guarantee. You don’t need to compare device limits, but keep in mind that devices share data. A computer may download files in the background while a mobile device streams content. Other devices may use data even when you’re only using one. Use the dashboard as your main reference for your balance. A client’s local statistics may only cover the current device or session, so the reporting scope may differ.

If you upgrade a monthly plan mid-cycle, the price difference is converted into remaining days. Before proceeding, read the change details and order information shown in the dashboard. Don’t calculate the result by subtracting full months yourself or assume the upgrade will issue your current data allowance again. For renewals, plan changes, or existing orders, read the confirmation page before continuing. If the displayed status doesn’t match what you expect, pause and keep the order details. Contact support through a ticket rather than submitting several different options, which can make the situation harder to review.

Use your needs to guide your choice

Use your actual records to estimate data for everyday browsing and text-based tools. If you regularly join meetings, consider connection stability as well as data allowance. For extended video viewing, account for both video quality and data use. A plan’s data allowance cannot guarantee a particular quality on a streaming platform; playback also depends on the route, local network, and platform policies. If you mainly stream video, read why video quality drops and which route metrics matter to understand these factors, then choose the right allowance on the plans page.

Once you’ve chosen, note the plan name, billing type, and how its data is handled. This will help you distinguish normal billing rules from an unexpected balance change, reset date, or renewal issue. For a full comparison, visit the plans and pricing page. This guide explains how to choose; the order confirmation page is the source of truth for your purchase. If you’re unsure, first consider how often you’ll use the service and which apps you need. You don’t have to configure everything or make every spending decision at once just in case you might need it later.

Create an account and check your order

Keep your account sign-in details safe

Z3VPN doesn’t require an email address. Create an account with a username and password. Open the user dashboard, enter your username and password as prompted, and check that they meet the requirements before submitting. Consider using a password manager to save the dashboard address and account details rather than relying on your browser’s temporary memory. Choose a username you can reliably recall, and don’t reuse a password from another service. After creating your account, make sure you’re signed in to your own dashboard before choosing a plan. Avoid creating multiple accounts in different browser windows, or your orders and subscriptions may end up under separate sign-ins.

Because your account isn’t tied to an email address, don’t assume it can be recovered through the email reset process common on other sites. Use the account management options actually available in the dashboard, and keep your username and password safe. On a shared device, don’t leave your account signed in; log out when you’re done. If you contact support about a sign-in issue, describe the error, steps taken, and device environment. Never send your password or use your full subscription link as proof of identity. Account credentials and support ticket details serve different purposes and should be handled separately.

Check before submitting; confirm after payment

When you open the plans page, double-check the plan type, price, and data allowance rather than relying on the card’s position. Switching pages, returning to browser history, or keeping an old tab open can make it seem as though your selection hasn’t changed. Read the order summary before confirming. If you already have a pending order, check its status before creating another. If payment is interrupted, check your order history to see whether it’s still pending. Don’t pay again just because the original page appears blank.

Payment methods include Alipay / WeChat Pay / USDT. Follow the instructions shown on the payment page for that transaction. For USDT in particular, verify the required network, recipient details, and amount. Don’t rely on chat messages, old screenshots, or details from previous orders, and don’t choose a network that the page doesn’t specify. If anything about the payment instructions is unclear, stop before transferring funds. The payment and dashboard order must correspond to each other. A debit shown in your payment app alone does not confirm that a plan is active in the dashboard.

After payment, return to the dashboard and check the order status and account overview to confirm that the plan appears. The payment result and dashboard status may appear in different places, so make sure they refer to the same order. If you’ve been charged but the dashboard hasn’t updated, keep the order reference, payment result, and transaction time, then request a review through a support ticket. Hide unrelated personal details in screenshots. Don’t create new orders to “force a refresh”: this won’t clarify the original order’s status and can make it harder to match records later.

Know when you’re ready for the next step

Move on to getting your subscription only after you’ve confirmed your plan status in the dashboard. Being able to open the client doesn’t mean your order is active, and a completed order won’t automatically install a configuration on every device. At this stage, confirm that you can access your account, the order matches your purchase, and the plan shown in the overview is what you expect. If any of these details are unclear, resolve the account or order issue first. Don’t jump into the client to change routes, proxy modes, or system permissions and introduce unrelated variables.

The service offers a 60-day money-back guarantee. See the Terms of Service for details. To discuss an order or request a refund, submit a ticket through the dashboard support portal and include the relevant order and request. Uninstalling the client does not cancel an order, and deleting a local configuration does not submit a refund request. Account services must be handled through the dashboard and support tickets. Installing, connecting, or deleting a configuration on your device only affects your local setup.

Get your subscription and manage configurations

Get your subscription from the dashboard

Sign in to the dashboard and find the subscription details and import options in your account overview. Subscriptions must be retrieved after signing in. Don’t copy purported universal links from public articles, forum attachments, or messages from unknown sources. A subscription link identifies the route list and may also contain authorization information needed for setup, so keep it private. When copying, make sure you select the whole link and don’t include explanatory text, quotation marks, or line breaks. After pasting it into your client, check that it’s recognized as a subscription source rather than a regular route note.

One-click import opens a client installed on your device. If your browser asks for permission to open an app, check its name before continuing. If no prompt appears, don’t keep clicking. First make sure the right client is installed and opens on its own, then try again from the dashboard. If your system can’t associate the import protocol with the client, use the manual subscription option in the client. The dashboard’s different import methods may be intended for different configuration formats. Don’t assume that a similar-looking link can be used in another client’s import option.

What to check when importing manually

In the client, look for an option such as “Add subscription” or “Import from URL.” Give the configuration a recognizable name, then paste in the subscription link. The name can help distinguish accounts or purposes, but it doesn’t need to include a password. Save it and update the subscription. Check whether a route list, rules, or configuration summary appears. Saving the link only adds a source; a successful update means the client has retrieved its contents. If the list is empty, check the update result or error message first. Don’t assume every route is down or rush to change system network settings.

The address below is only an example of the format, not a real subscription, and cannot be used to connect. Always get your actual link from the dashboard after signing in. Parameters after the question mark are part of the subscription link; don’t remove them to make it “look cleaner,” and don’t use an unknown website to shorten or convert the link. Browsers, chat apps, and clipboard managers may save copied text. On shared devices, check where the link is going. Don’t paste it into a public search box, online translation tool, or screenshot description.

https://example.com/sub?token=YOUR_TOKEN

If an update fails, troubleshoot in this order: source, network, format. Confirm the link came from the dashboard for your current account, check that your device has a working internet connection, then verify that the selected client supports the format. If the response is actually a sign-in page or plain text error, the client usually can’t parse it as configuration. Go back to the dashboard and check your account and plan status rather than repeatedly renaming the subscription. Don’t share your subscription link on third-party testing sites. If you need help, describe the update error and remove the full link from anything you submit.

Distinguish remote content from local choices

Updating a subscription retrieves new remote content and may change the route list, groups, or rules. Whether manual local changes are kept depends on how the client manages its configuration. Use the client’s local override or separate settings options where possible, rather than making extensive edits directly to auto-generated subscription content. Before experimenting, back up any local settings you may need to restore, and note which parts are managed by the subscription. That way, if something changes after an update, you can tell whether the remote list changed or a local edit was overwritten, instead of mistaking a normal sync for a problem.

You can use one subscription on multiple supported devices, but unlimited devices doesn’t mean you should share the authorized link publicly. Import, update, and verify the connection separately on each device. Success on one device doesn’t confirm that another has the right permissions or proxy mode. If you think the link has been exposed, check whether the dashboard offers a way to reset it, or ask support through a ticket. After a reset, older devices may need to import the subscription again. Plan the update so you don’t interrupt work that depends on an outdated configuration.

Client setup and permissions by platform

Get clients from the dashboard download page. Sign in to download a client for Windows / macOS / Android / Linux; you don’t need a paid plan. You must still sign in to get your subscription. The iOS client download also requires an active plan. Downloads and subscription access are separate: getting the app doesn’t mean you have a usable route. After installing the client, open it once before importing from the dashboard. This makes it easier to tell whether a failed import is due to the browser being unable to open the app.

Windows and macOS

After installing on Windows, make sure the client opens properly before importing and updating your subscription. When you enable the connection for the first time, check any permission prompts from Windows or security software. Confirm the source and purpose before approving them. If you use system proxy mode, check the status shown in the client. If you use a virtual network adapter, complete the required permissions or component setup. Don’t let another proxy tool take over the system settings at the same time. Closing the window may only minimize the app to the system tray. If you’re troubleshooting a conflict, check whether it’s still running in the background instead of relying on whether its window is visible.

On macOS, first place the app as directed in the dashboard, then grant any permissions required by the system. If prompted to approve a network extension or VPN configuration, make sure you recognize the app before approving it, then check its status in the client. System proxy settings and the client’s connection toggle may operate at different levels; confirm your network is back to normal before quitting the client. If your browser works but other apps don’t, first check whether those apps use the system proxy before trying another connection method. Don’t change system DNS settings at the outset or install an unknown certificate as a routine connection step.

iOS and Android

On iOS, first confirm that your plan is active in the dashboard, then download the appropriate client. After installing it, import your subscription and allow it to add a VPN configuration when prompted. This system prompt confirms network access; it doesn’t ask you to purchase your plan again. Return to the app, choose a route, and connect. Check both the client status and the system’s connection indicator. To disconnect, use the client and confirm that the system status changes too. For illustrated step-by-step instructions, see the iPhone setup guide for beginners.

On Android, import your subscription and update it after installing the client. Grant VPN permission when prompted to connect. If the connection often drops when you switch apps or lock your screen, check the system’s background and battery restrictions for the client before changing every route. Settings names vary by device; look in the app info page for options related to background activity, battery use, or autostart. Change only the settings relevant to this client, and note their original values. For the full walkthrough, see the Android installation and background settings guide.

Linux and cross-platform differences

On Linux, choose a client suited to your environment based on the dashboard instructions, then check that it can load your subscription. A desktop system proxy usually affects only apps that follow that setting; terminal programs, background services, and other user sessions may not inherit it automatically. If you use network routing, configure the required permissions according to the client documentation. Don’t run every program with elevated privileges indefinitely. After importing, test the apps you use most, then configure terminal or development tools as needed. Linux distributions and setups vary, so use the specific error message to guide troubleshooting. Don’t copy a full network configuration from an unknown source.

Platforms share your account and subscription, not all system settings. A successful setup on your computer doesn’t mean your mobile device has the required permissions. A failure in a terminal program doesn’t mean the entire client is broken. Keep a separate check for each device: whether the configuration updated, permissions were granted, which route is selected, and whether the target app works. These notes are more useful than simply recording that the app is installed, and they give you a clear recovery sequence if you switch or reinstall a device.

Verify your exit location and apps after connecting

Check the connection first, then verify your exit location

Choose a route and connect in the client. Check that it clearly shows a connected status, then open the What’s my IP page to verify your exit location. An IP lookup shows the network path used by that browser request; it doesn’t verify every app. If the location doesn’t match your selection, check whether your browser has its own proxy extension, whether the client is in direct mode, and whether rules are routing the lookup request elsewhere. Don’t assume all traffic is routed just because an icon appears, or that a target service will work just because your exit location changed.

If the IP lookup doesn’t return a result, try a regular webpage to check basic access, then review the client log. A tool displaying no information doesn’t necessarily mean the connection failed. Check whether the request was sent, whether a response came back, and where the error occurred. Keep your local network unchanged during testing; don’t switch Wi-Fi and change routes at the same time. Otherwise, even if things improve, you won’t know whether it was due to local connectivity or the cross-border route, and you won’t have a reliable result to use next time.

Understand proxy modes and app behavior

Rule mode uses the configuration to decide which requests use a route, making it suitable for directing traffic based on its destination. Global proxy mode covers more traffic, but is still limited by what the client can actually route. A system proxy only applies to programs that use that setting. Virtual network routing involves broader network handling and permissions. These are not performance tiers; “global” doesn’t mean faster. When troubleshooting an app, temporarily change one mode while keeping the original configuration, and observe the difference. Restore the setting that fits your everyday needs when you’re done.

If the exit location has changed but an app still reports a region mismatch, check the app’s account region, existing sign-in session, and supported regions. Streaming platforms may also use content licensing, payment region, or account settings to determine what’s available. AI tools may have their own regional and account policies. A route provides a connection path; it doesn’t replace these eligibility requirements. Try fully closing and reopening the app, or retest in a separate browser session to rule out stale connections and cached data. Don’t repeatedly clear all your data instead of troubleshooting the specific issue.

Check consistency, not just a one-time result

Once a webpage loads, test the task you actually want to do. For meetings, check that audio and video stay consistent. For video, look for stable playback and picture quality. For development tools, verify that sign-in, requests, and file transfers all work. Different features may use different domains and connection methods, so loading the homepage doesn’t confirm that uploads, real-time responses, or background sync work too. Test under normal conditions. Don’t close every app you use just to get a good one-off result, then blame the route name when everyday performance differs.

When comparing backup routes, use the same destination service under similar conditions, and keep your original working route. Change one thing at a time: try another route in the same region first, then try a different region if needed. If every route fails, check your basic network, plan status, and subscription update rather than cycling through the entire list. If only one app fails, focus on its routing rules, account status, and settings. For remote work, see the guide to choosing routes for meetings to understand the difference between consistency and responsiveness.

After testing, you should be able to say which route and mode you’re using and which apps you’ve confirmed work. If all you can say is “it works sometimes,” your test conditions aren’t clear enough. Record a working setup as your everyday baseline and keep one tested backup. If something goes wrong later, return to the baseline and compare one factor at a time. This avoids unproductive switching and gives support useful details: whether the issue is ongoing or occasional, affects one app or the whole device, and changes when you switch routes.

Routine maintenance, data use, and renewals

Keep a stable baseline and update when needed

You don’t need to rebuild your configuration constantly. Keep routes and modes you’ve verified as your stable baseline. Update your subscription when the route list changes, a route disappears, or the dashboard prompts you. Before updating, make sure you don’t have an important meeting, transfer, or long-running task underway; reloading the configuration may interrupt the connection. Afterward, check whether your original choice is still available and select a route again if needed. If your local network only had a brief interruption, don’t immediately delete the entire subscription. Restoring it would then require dashboard access and a fresh import.

Manage client updates and subscription updates separately. A client update changes the app itself; a subscription update retrieves routes and configuration. The former won’t necessarily fix account or data allowance issues, and the latter won’t grant missing system permissions. Before updating the client, note your configuration name, mode, and working routes. Afterward, check whether those settings remain. Don’t delete all your old records before verifying the update. If something isn’t compatible, describe what changed before and after the update instead of only saying “it stopped working after the update.”

Understand data usage and reset dates

Monthly plan data resets each month on the activation date, not necessarily at the start of the calendar month. When checking usage, confirm your plan type and the relevant dates shown in the dashboard. Data packages last until used, never expire, and don’t refill monthly. Unlimited devices means you can use the service on supported platforms; it doesn’t mean background data use can be ignored. If usage is higher than expected, check for ongoing playback, downloads, or sync tasks across your devices. Compare dashboard changes with actual activity rather than judging usage only by the app currently on screen.

Client usage, operating system network statistics, and dashboard statistics may cover different things. A client may record only the time its process is running; the system may include requests that don’t use a route; and the dashboard reflects account-level usage. Don’t try to match them one by one without understanding what each measures. First clarify what you’re checking: one device, the current client, or the whole account. If multiple devices are in use, pause unnecessary background tasks temporarily and monitor the change so you don’t mistake another device’s traffic for a problem with the current app.

Renewals, upgrades, and switching devices

Before renewing, check your current plan and orders in the dashboard. Then open the plans page and confirm what the new action will do. Don’t assume a new order will always be added separately to the old plan or infer how balances are handled from the appearance of a plan card. For a mid-cycle monthly plan upgrade, the price difference is converted into remaining days; rely on the confirmation page for the actual change. If you plan to switch from a monthly plan to a data package, or the dashboard shows an unclear replacement notice, confirm the details through a support ticket first. Resolve questions about the purchase before submitting. Client settings cannot change billing type or order rules.

When switching devices, install the client, import your subscription, and verify it on the new device before deciding whether to remove the old one. Exported configurations may contain subscription links or other sensitive information; don’t sync them publicly like ordinary documents. If you’re no longer using the old device, sign out of the dashboard, remove the client configuration, and delete relevant backups. Keeping your account sign-in details doesn’t mean you need to retain complete connection data on every old device. When you need to set up again, signing in to the dashboard for the current subscription is usually easier to verify than sharing an outdated configuration, and it also helps confirm your current plan status.

When your needs change, review your actual usage and tasks before changing your plan or route. A low data balance, a dropped connection, and a destination platform’s restrictions are different problems; upgrading won’t solve all of them. For refund requests or billing questions, read the Terms of Service and submit a ticket through the dashboard. The service offers a 60-day money-back guarantee. When you stop using the client, also check for proxy settings left on your device and make sure your regular network connection works. This prevents local routing from interfering with access after you quit the app.

Advanced routing and troubleshooting

Narrow down problems along the connection path

Advanced troubleshooting isn’t about changing more settings; it’s about making each change test a clear hypothesis. First sort the issue into one of three types: subscription retrieval failure, connection failure, or app failure after connecting. For subscription failures, check the source and account status. For connection failures, check permissions, the local network, and the selected route. For app failures, check routing rules, DNS resolution, and account requirements. Once you know which layer is affected, you won’t need to reinstall the client, change DNS, and switch regions all at once. A minimal, repeatable test is more useful than trying many settings at once.

Rules, DNS resolution, and local resources

Routing rules determine which path a request takes. DNS resolution converts a name into an address the device can connect to. Successful DNS resolution doesn’t guarantee the connection will work, and a changed exit location doesn’t mean all DNS requests use the same path. If a website’s homepage loads but some resources fail, check whether the client handles those requests differently, then investigate DNS errors. Don’t treat random changes to public DNS servers as a permanent fix: they may change how local sites, corporate networks, or apps behave and introduce more uncertainty.

Using broader network routing may affect local devices, development environments, and company resources. If printing, shared folders, or internal sites stop working, first check whether their requests are being sent along an unsuitable route. Use the client’s existing LAN or direct connection settings to investigate, but don’t delete the entire rule set. Work devices may also be managed by your organization, so check its policies before changing network settings. Verify access to international services separately from access to local resources, and record the results as two distinct checks.

Proxy settings for development tools and log details

Development tools such as Cursor may use separate processes for the interface, extensions, and terminal tasks. A successful browser connection doesn’t mean these processes use the same proxy. First check the tool’s own network settings, then see whether its launch environment affects proxy inheritance. Don’t blindly enter a local port from an online example: the port and protocol must match what your client is actually listening on. If you’re unsure which proxy type it uses, check the client’s documentation rather than trying the same address in every field. For more on regional access to AI tools, see the AI Tools guide.

To inspect the terminal environment, Linux and macOS users can run the command below to check for proxy variables in the current process environment. It only displays existing variables; it won’t configure a proxy or prove that an app follows those variables. Don’t share output that includes internal addresses, usernames, or credentials. No variables appearing in the terminal doesn’t prove the system proxy is inactive. This check only helps narrow down the cause and should be considered alongside client logs, app settings, and actual request results.

printenv | grep -iE '^(http_proxy|https_proxy|all_proxy|no_proxy)='

When submitting an issue through a dashboard support ticket, include your operating system, steps taken in the client, selected region, proxy mode, exact error text, and tests you’ve already performed for comparison. Include only relevant log excerpts and remove subscription links, account credentials, and unrelated personal information first. “Switching to another route in the same region fixed it” is more useful than “all routes are slow.” “The browser works, but the terminal doesn’t” is more specific than “the network is broken.” Once resolved, add the confirmed steps to your baseline notes, remove unsuccessful test settings, and return to your normal setup.
