When comparing multi-device VPNs, start with how limits are defined, not just how many devices your household owns. For family use, installation count, simultaneous connections, and shared data are separate considerations. VPNKN has no device limit, but data is still governed by the selected plan; having more devices does not mean each one gets a separate allowance.
Device limits: installations, connections, and exit IPs
“Supports multiple devices” only means the service can be used on more than one device; it does not necessarily mean those devices can connect at the same time. Before choosing a subscription, check exactly what the plan counts. In particular, distinguish account sign-ins, client installations, and active proxy connections rather than treating them as the same thing.
| Limit type | What is usually counted | What families should check |
|---|---|---|
| Installed or authorized devices | Devices linked to an account or granted authorization | Whether an old device must be unlinked when replacing a computer |
| Simultaneous connections | Active devices or sessions at the same time, as defined by the service | Whether a connection kept running in the background still uses a slot |
| Exit IP addresses | Different public IP addresses used to access the service | Whether using home broadband and a mobile network at the same time triggers a limit |
| Data allowance | Billable data accumulated under the subscription | Whether data is shared across the account and how uploads and downloads are counted |
Some proxy clients create multiple connections for different requests, so the number of entries in connection logs is not the number of devices. Exit IPs are not a direct measure of device count either: devices on the same home network may share a public exit, while the same device may show a different exit after changing networks. Always follow the service's specific limits.
VPNKN's no-device-limit policy removes restrictions on the number of devices; it should not be taken to mean unlimited data or bandwidth, or permission to share a subscription publicly. Check the terms of service to confirm whether family sharing or use from different addresses is allowed. Device policies do not replace account-use rules.
Disconnects after exceeding a limit: identify the restriction first
Services with device or session limits may reject new connections, end an existing session, or ask you to remove an authorized device first. These are common approaches, but not every service handles limits the same way. If one device disconnects just after another connects, that alone does not prove the account has been restricted.
If all devices at home slow down at once, check the local broadband connection, Wi-Fi, and remaining account data first. If only one device has a problem, check its system proxy settings, client status, and background permissions. If only one website fails, check the routing rules, DNS, and the website itself instead of repeatedly importing the subscription.
- ✅ Check remaining data and subscription status in the dashboard to rule out a depleted allowance or expired subscription.
- ✅ Pause connections on other devices and test the same device on the same route to reduce variables.
- ✅ Compare the home network with another available network to see whether the issue follows the local connection.
- ✅ Note the error message and circumstances. When submitting a support ticket, hide subscription URLs, passwords, and authentication details.
VPNKN has no device limit, so there is no need to assume that adding another device at home is the main cause. However, multiple devices downloading at once still compete for local bandwidth and use the plan's shared data. Device limits and actual network capacity are separate constraints.
Sharing a subscription with family: estimate data, then choose billing
Household data use is rarely evenly distributed. Browsing and text-based work are usually light, while extended video streaming, large file synchronization, and system updates can consume data in bursts. Rather than assigning an arbitrary allowance to each person, check actual usage in the client and dashboard first, and identify which apps account for most of it.
The client may show usage for only the current device, session, or a subset of connections; the dashboard accumulates usage according to the service's billing rules. The figures may not match exactly. For a household budget, use the dashboard's allowance as the main reference and client statistics to identify high-usage apps. Do not add numbers from different sources without checking what they represent.
| Billing option | Price and allowance | Allowance period | Best suited for |
|---|---|---|---|
| Monthly subscription | ¥9.9 / 60GB; ¥18 / 250GB; ¥28 / 500GB | Resets monthly on the activation date | Ongoing family use with relatively predictable monthly usage |
| Data package | ¥158 / 300GB; ¥358 / 1000GB; ¥658 / 3000GB | Valid until used; never expires | Infrequent use when you do not want a monthly data reset |
Monthly subscriptions suit ongoing access needs, while data packages work better for irregular use. A data package never expiring does not mean it will always cost less for every household. Compare the allowance you expect to use and your usage patterns rather than choosing only by the larger figure on a plan. See the plans page for full details.
VPNKN supports mid-cycle upgrades, with the price difference converted into remaining days. Estimate your household's total usage before choosing a tier; an upgrade does not mean extra data is added. The refund policy provides a 60-day no-questions-asked refund. Check the dashboard and terms of service for the process and details.
For frequent shared use, compare monthly subscriptions based on your household's total usage. For occasional access to international websites, consider a data package that never expires. No device limit reduces the work of managing devices, but it does not replace a data budget.
Importing subscriptions: configure each device and keep links private
Subscription links usually contain credentials needed to configure access routes, so treat them as sensitive information. They are not ordinary tutorial URLs and should not be posted in public groups, screenshot comments, or online conversion tools. When helping family members configure a device, share the link directly between trusted devices to avoid widening access unintentionally.
- Check the platform and client. VPNKN supports Windows, macOS, iOS, Android, and Linux. Get the relevant instructions from the dashboard client page, and first confirm that the operating system and client are compatible.
- Get the subscription from the dashboard. Copy the subscription URL provided by the service, add it from the subscription or configuration management section of the client, and wait for it to finish loading. Do not enter your account password in the subscription URL field.
- Check format compatibility. Clients use different configuration formats and support different protocols. If importing fails, first check whether you selected the wrong format instead of modifying authentication details in the link.
- Grant the required permissions. Enable the necessary network permissions as prompted by the operating system, then choose a route and rule mode. Verify each device separately; a successful setup on a computer does not mean other devices are configured correctly.
- Test commonly used apps. Open apps that need international access and local services that should connect directly. Check their routes and connection logs before deciding whether to enable automatic connection.
Shadowsocks, VMess, Trojan, and VLESS are names for proxy protocols or protocol families. They do not mean every client supports them or that a current VPNKN subscription necessarily includes them. Choose a client based on the configuration actually provided in the dashboard, not just on protocol names when judging speed or stability.
Family routing: separate local and international access
Rule-based routing can send requests that need international access through subscription routes while keeping services suited to local access on their usual paths. This can reduce unnecessary plan usage, but only if the client actually handles traffic from the relevant apps. When only the system proxy is configured, some apps may ignore it; do not assume this covers every connection.
Tunnel mode usually covers more traffic, but it requires the relevant system permissions and may affect local network discovery, printing, and home file sharing. If these features stop working, check that private network addresses are set to connect directly and whether the client has an option to allow local network access. Do not delete all the rules just to get a printer working again.
Check DNS alongside routing rules
A DNS leak usually means domain lookup requests are not sent along the expected route. A website request going through a proxy does not mean its DNS lookup also does. Check the client's DNS mode, encrypted DNS settings in the operating system, and whether the browser uses a separate resolver. When these settings overlap, DNS and connection requests may take different paths.
If a local service resolves to an unsuitable address, or an international website resolves correctly but will not connect, check DNS results and connection logs separately. An exit IP lookup page alone cannot prove that every DNS request follows the expected route, or that every app is being handled.
Route types are not a measure of device limits
IEPL, transit, and direct connections describe different route arrangements. IEPL usually refers to international Ethernet private-line transport, transit routes pass through forwarding nodes, and direct connections generally do not pass through an additional relay operated by the service. Actual performance still depends on the route, congestion, and local network conditions; the name alone cannot guarantee the experience when a household uses the connection on several devices at once.
Maintain each platform: reduce background interruptions and repeated setup
On Windows and macOS, check for leftover system proxy settings and other network tools that may also be handling connections. On Android, review battery optimization and background activity restrictions so the system does not pause the client after the screen locks. On iOS, check the active network configuration and the client's actual support for rules and protocols.
Linux desktop environments, background services, and app proxy settings can all differ. Proxy environment variables set in a terminal may not affect graphical apps, and the reverse can also be true. When maintaining devices, be clear about which apps rely on the system proxy and which use tunnel mode so family members do not assume that an open client means every program follows the same route.
Connecting through a home router can reduce per-device setup, but only if the device, firmware, and client support the required configuration. A no-device-limit policy does not mean every router will work out of the box. Centralized connections also make troubleshooting more dependent on the router, so keep a recoverable configuration before changing rules.
The goal is not to find a single “fastest node,” but to have a repeatable way to check the setup: review the remaining allowance, confirm the client is connected, check the rules, and then switch routes if needed. VPNKN does not require an email address for registration. When managing access as a family, keep account credentials secure and do not use the account password as a way to share subscriptions day to day.
