When choosing a VPN for multiple devices, the key question isn’t how many clients you can install. It’s whether everyone in your household can connect at the same time, how data is pooled, and whether the service allows the way you plan to share it. Before comparing prices, check the account’s sharing terms, connection limits, and platform support. VPNYJ’s unlimited-device policy makes it worth considering, but it doesn’t mean unlimited data or confirm that every sharing arrangement is permitted.

Device limits and simultaneous connections are different

“Device limit” can mean different things from one service to another. Some limit how many devices can be linked to an account; others let you install the app on multiple devices but cap the number of connections online at once. Some track active sessions or access addresses instead. Before choosing a plan, find out exactly what’s being counted rather than relying on the words “unlimited devices.”

Installing a client usually just puts the software on a device; it doesn’t necessarily use up a connection slot. Whether a connection counts once established, and when a session is released after a device goes to sleep, depends on the service’s rules. Background connections, sleep mode, and network changes can also cause the status shown on your device to differ temporarily from the server’s records.

Limits to check when comparing services
Limit What it means What families should ask
Device installation or linking Which devices can save the account or be registered Do you need to unlink an old device when replacing a computer?
Simultaneous connections The number of connections or sessions allowed at the same time Will family members knock one another offline when they connect at the same time?
Data allowance The total amount available per billing period or data plan Do all devices on the account use the same data allowance?
Sharing permissions Who may use the account and in which situations Do the terms allow family members to use the account and connect from different locations?

Services also handle connection limits differently. Some may reject a new connection, end an existing session, or require you to remove a linked device first. If a newly connected device works while an older one disconnects, check the simultaneous-connection policy before assuming there’s a network issue.

Before sharing an account with your family, check the permissions

An unlimited-device policy describes the number of devices; it doesn’t automatically allow public sharing, reselling a subscription, or handing account access to anyone. Check the terms or ask customer support whether family sharing and connections from different locations are allowed. The confirmed detail about VPNYJ is that it has no device limit; this guide doesn’t infer any unpublished sharing permissions from that.

Account login credentials and subscription links don’t grant the same kind of access. Login credentials are generally used to manage a plan and account settings. A subscription link may contain an access token that can retrieve server configurations. Sending one to a family member may be convenient, but it still shares access credentials—don’t post it in public group chats, publicly accessible notes, or screenshots.

Separate accounts make it easier for family members to manage their own payments, data, and configurations. If one person manages the account and the sharing arrangement has been confirmed, a shared account can avoid setting everything up more than once. There’s no single right answer: it comes down to whether easier management or separate access controls matter more.

With unlimited devices, the real limit to watch is data

Adding more devices to a household doesn’t automatically add more data. Devices billed to the same account draw from a shared allowance; whether their traffic uses that account depends on client routing rules and how each app connects. Video streaming, cloud file transfers, operating system updates, and background syncing can use data more steadily than text-heavy websites.

A monthly plan can suit households with regular usage. VPNYJ’s monthly data allowance resets each month on the activation date—not automatically at the start of the calendar month. A data plan may suit less predictable usage; it never expires, but its allowance is still limited and you’ll need to plan for more once it’s used up.

VPNYJ billing options
Billing option Price and data allowance How the allowance works
Monthly plan ¥9.9 / 60GB;¥18 / 250GB;¥28 / 500GB Data resets monthly on the activation date
Data plan ¥158 / 300GB;¥358 / 1000GB;¥658 / 3000GB Never expires

When you start, keep an eye on the usage shown in your dashboard and how each device is used; don’t choose a large allowance based on household size alone. If you upgrade mid-cycle, VPNYJ converts the price difference into remaining days. If you have both a monthly plan and a data plan, check the dashboard or ask customer support which allowance is used first—don’t assume the system always draws from one particular plan.

Set up each platform separately instead of forcing one configuration onto every device

VPNYJ supports Windows, macOS, iOS, Android, and Linux. Platform support doesn’t mean every client has the same interface, network permissions, or settings. Download the right version from the client downloads page, then follow the setup guides to configure it.

  1. Check the source and platform. Verify where the installer came from, the system requirements, and the processor architecture. Don’t install an app just because its filename looks familiar, and don’t follow setup instructions intended for another platform.
  2. Sign in or import the configuration as instructed. If the client requires a subscription link, paste it into the designated field and update the configuration. A successful import means the configuration was readable; it doesn’t confirm that every server can connect.
  3. Approve the required network permissions. Desktop systems may ask you to enable a network extension, while mobile devices may prompt you to add a VPN configuration. Make sure the prompt matches the client you’re installing.
  4. Choose a route and verify the connection. After connecting, open an app you actually need to use, then check your exit address on the IP lookup page. A changed client button color isn’t enough to verify that everything is working.
  5. Test everyday network changes. Check whether the connection recovers after waking from sleep or switching between your home network and another network. Make sure family members know how to spot a dropped connection.

A subscription is a way to distribute configurations, not a network protocol. Whether protocols such as Shadowsocks, VMess, Trojan, and VLESS are available depends on the server configuration and client implementation. Being able to import a subscription doesn’t mean the client supports every protocol it contains. Don’t change protocol fields just to use a newer-sounding name; this guide doesn’t list any unconfirmed protocol as a VPNYJ feature.

Desktop clients and command-line setups on Linux may require different configuration steps. On mobile devices, check whether battery-saving settings prevent the connection from resuming in the background. For platform-specific issues, follow the guide for that platform instead of repeatedly copying settings from another device.

Split tunneling and route selection shape the shared experience

Family members don’t all have to use the same route. Streaming, remote work, and everyday browsing may call for different regions. VPNYJ offers 110+ countries and 230+ routes, giving you options, but that doesn’t guarantee the same experience from every location at every time.

IEPL, relay, and direct connections describe how a route is set up, not which client protocol it uses. IEPL generally refers to a connection carried over a dedicated line; a relay routes traffic through an entry server, while a direct connection links the device to the relevant server. Entry-point quality, network paths, and congestion at the exit can all affect performance, so a route’s name alone can’t tell you which one will be fastest.

Routing rules determine which requests use the proxy and which connect directly. Rule-based mode can make it easier to handle local services and international access separately, but the rules need to be maintained. Global proxy mode doesn’t necessarily route every app or all system traffic either. The actual path can depend on whether the system proxy or a virtual network adapter is in use and whether each app follows the system settings.

Check DNS as well. If app traffic goes through the proxy while DNS queries take an unexpected route, you may see a DNS leak or mismatched results. A browser’s encrypted DNS settings, the client’s DNS policy, and system resolver settings can interact. Checking the exit IP once isn’t enough to confirm DNS is behaving as expected; use the client’s documentation and DNS tests too.

Troubleshoot disconnects and connection limits step by step

If family members have trouble connecting at the same time, don’t assume there are too many devices on the account. A single-device issue, unstable home Wi-Fi, an exhausted data allowance, or congestion on a particular route can all make websites unreachable. First work out how many devices are affected, then change settings one at a time so you can compare the results.

  • ✅ Only one device is affected: Check its configuration, network permissions, system time, and any conflicting network tools.
  • ✅ All devices are affected: Check the account status, remaining data, and home network, then try a different route.
  • ✅ Only one app is affected: Check its proxy settings, routing rules, and the status of the service you’re trying to reach. Don’t rush to reinstall every client.
  • ✅ A new device connects but an older one disconnects: Check the service’s session-counting and sharing policies, and save any error messages for customer support.
  • ❌ Don’t post a full subscription link, login credentials, or screenshots of configurations containing access tokens while troubleshooting.

If the issue only happens on your home Wi-Fi and goes away on another network, check Wi-Fi coverage and your router. If the same device works after switching routes, the route itself may be the issue. When asking for help, include the operating system, client, network, what you were doing, and a redacted error message; that’s more useful than simply saying “it doesn’t work.” You can also continue troubleshooting on the diagnostics page.

Choosing the right way for your family to share one account

If you only take turns using a few devices, unlimited devices may not need to be your top priority. If several devices are often connected at once, a clear device policy matters more. If the main issue is running out of data, more device slots won’t help; if family members need to manage their accounts separately, a larger data allowance can’t replace separate access controls.

VPNYJ’s unlimited-device policy, platform support, and two billing options make it a useful point of comparison for these needs. The service also offers a 60-day no-questions-asked refund and accepts Alipay, WeChat Pay, and USDT. Choose based on your sharing permissions, typical data use, and device compatibility; a refund policy is not a measure of performance.
