VPN Beginner FAQ: Answers to the 10 Most Searched Questions

Can you use a VPN on multiple devices, how is data measured, will speeds be throttled, and how do refunds work? Ten common beginner questions answered.

VPN beginner questions are usually not just about whether a connection works. They are also about data usage, choosing a route, how changing an exit affects account sessions, and importing a subscription link. This guide starts with real-world scenarios and provides practical answers you can check and apply.

Devices and Data Usage

Question 1: Can I use the VPN on multiple devices at the same time?

Yes. VPNKF supports simultaneous connections on any number of devices. The same subscription can be imported on a computer, tablet, and other compatible devices. “Unlimited devices” means there is no fixed device-count limit; it does not mean each device gets separate data. All devices still share the allowance in the current plan.

When several devices are connected at once, data is often used faster than with a single device. System updates, cloud sync, video preloading, and background apps may continue transferring data. If usage changes noticeably, pause background syncing on each device first and watch whether the dashboard stabilizes. This is more useful than immediately assuming the route is at fault.

Question 2: How is data used and when does it reset?

Browsing websites, downloading files, watching videos, making voice calls, and syncing data all generate network traffic. The instantaneous speed shown by the client and the plan usage recorded in the dashboard are different concepts: the former describes the current transfer rate, while the latter records how much plan data has been used.

VPNKF monthly subscription data resets each month on the activation date. The activation date is not the first day of the calendar month, so do not rely on the calendar alone to decide whether your allowance should have returned. Data packages do not expire, making them suitable for irregular usage and pay-as-you-go consumption. Check the user dashboard for the exact remaining allowance and reset status.

Bottom line: device count and data allowance are separate concepts. VPNKF does not limit the number of simultaneous devices, but multiple devices share the same plan data; monthly subscriptions reset on the activation date, while data packages do not expire.

Speed Changes and When to Connect

Question 3: Does slower speed mean I am being throttled?

Not necessarily. A network acceleration path includes local access, carrier routing, the entry server, the international link, the exit server, and the destination website. Congestion at any point can cause slow downloads, video buffering, or longer initial page loads. A data allowance is not the same as real-time speed, and the two should not be confused.

To diagnose the issue, first confirm that the local network works normally with the proxy disconnected. Then connect to a nearby route and test a regular webpage, followed by the target service. If only one website is slow, the cause may be the destination or its corresponding exit. If every route is slow, check the local Wi-Fi, client mode, and background system tasks.

Symptom Check first Next step
No route can connect Local network, subscription updates, system time, and firewall permissions Switch protocol or network environment and test again
Only a specific region is slow Distance to that region and current congestion Choose a nearby region or a different route type
Websites load normally but videos buffer Video quality, exit region, and the destination service’s policies Reduce concurrent downloads and verify the exit again
Local websites become slower after connecting Whether global proxy mode is enabled Use split tunneling so local traffic connects directly

Question 4: Do I need to keep the VPN on all the time?

There is no single answer. Keep it connected when you need international websites, an exit in a specific region, or protection on a public network. If you only use local services and have no need for an international route, disconnect or use split tunneling. A long-running global connection can send local traffic on an unnecessary detour, increase the route distance, and consume plan data.

A more practical approach is to set rules by domain, application, or network destination. Send international services through the proxy, connect local services directly, and keep LAN addresses direct. This reduces unnecessary detours and prevents printers, storage devices, and router admin pages from becoming inaccessible because of global proxying.

Rule strategy
Local services and LAN addresses → DIRECT
Domains requiring international routes → PROXY
Traffic that matches no rule → Decide based on actual needs

Rules are ordered and are usually matched from top to bottom. An overly broad rule placed first may override more specific rules later. If traffic still uses the proxy even though you clearly specified a direct connection, check the rule order and the client’s current mode before adding duplicate rules.

Switching Routes and Account Sessions

Question 5: Will changing routes log me out of a website?

It may, but not every time. Changing routes changes your public exit IP. Some websites treat a region change, frequent exit changes within a short period, or a changed session environment as a signal that additional verification is needed. They may ask you to sign in again or end the existing session. This is the destination website’s account-security policy, not a sign that the VPN subscription has stopped working.

When you need to stay signed in for an extended period, prefer the same region and one consistently performing route. Avoid switching between regions repeatedly while working. You should also avoid changing the exit suddenly before uploading a file, submitting a form, making a payment, or saving an online document, because the existing TCP or QUIC session will usually be interrupted.

Question 6: What is the difference between direct, relay, and IEPL routes?

A direct route connects your network straight to an overseas entry point. The path is simple, but performance depends heavily on the local carrier’s international exit and routing quality. A relay route first connects to a nearby relay entry point, which then forwards traffic to the target exit. This can improve routing, but it also adds another forwarding hop.

An IEPL route generally uses a dedicated international Ethernet link for the cross-border segment, with a different path structure from a normal public-internet direct connection. It does not mean the route will always be fastest in every location and at every time. Local access, entry-point load, and the path from the exit to the destination still affect the final experience. Choose based on whether the target service loads reliably, not on the route name alone.

Route type Path characteristics How to evaluate it
Direct Local network connects directly to an overseas entry point Test the actual performance from the local carrier to the target region first
Relay Connects to a relay entry point first, then forwards to the exit Compare how different entry points improve routing on the current network
IEPL Uses a dedicated link for the cross-border segment Focus on target-service loading, sustained transfers, and evening performance

Choosing a Protocol and Importing a Subscription

Question 7: How should I choose between Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC?

These names describe different proxy protocols or transport methods. Shadowsocks has a relatively simple structure and broad client compatibility; VMess belongs to the V2Ray ecosystem; VLESS separates identity verification from encrypted transport and is often paired with TLS or other secure transport layers; Trojan is typically carried over TLS.

Hysteria2 and TUIC use QUIC-based transport and have corresponding requirements for UDP availability and the network environment. On networks with packet loss or instability, they may behave differently from traditional TCP-based options, but they are not faster on every network. Enterprise, campus, or some public networks may restrict UDP; in that case, switch to a compatible TCP-based option.

Beginners do not need to guess performance from a protocol name. Start with the default route provided by the subscription. If the connection fails, check whether the client supports the protocol, whether its core is up to date, and whether the system time is accurate. A configuration that reliably reaches the target service is usually more suitable than one with the most parameters.

Question 8: How do I import a subscription link into a client?

A subscription link is the client’s entry point for reading node configurations. It may contain credentials required to access the subscription, so protect it like a password. The correct process is to copy the subscription address from the VPNKF user dashboard, open subscription management in a compatible client, paste the address, and run an update. Then choose a node from the updated route list.

  1. Get the current subscription link from the user dashboard instead of manually assembling one from chat history or an old screenshot.
  2. In the client, choose “Import from URL” or an equivalent option rather than pasting the link into a browser.
  3. Run a subscription update and confirm that the route names appear in the client list.
  4. Choose a node and enable the system proxy, VPN mode, or the corresponding connection mode provided by the client.
  5. Open a webpage to check the exit region. If it fails, review DNS, handshake, or timeout details in the client log.

When routes are adjusted later, you usually only need to update the existing subscription instead of creating multiple identical entries. Repeated imports can create configurations with the same name but different update times, making it difficult to tell which one is currently in use.

Bottom line: protocols do not have a fixed ranking independent of the network environment. Confirm client compatibility first, then test with the actual target service. Import and update subscriptions through the client, and store the link securely.

DNS, Split Tunneling, and Platform Differences

Question 9: What is a DNS leak, and how can I check whether split tunneling is working?

DNS translates domain names into network addresses. After connecting to a proxy, the target traffic may pass through the proxy while DNS queries are still sent directly to the local network’s configured DNS. This mismatch is commonly called a DNS leak. It may expose the domains being queried or cause access problems when the DNS result does not match the proxy exit region.

When troubleshooting, first check whether the client is handling DNS, then look for other network tools enabled on the system. Encrypted DNS in the browser, private DNS in the operating system, the client’s built-in DNS, and DNS assigned by the router may all coexist. If these settings conflict, changing only one of them is not enough to draw a conclusion.

Whether split tunneling is correct depends on where the target connection ultimately goes. Check the matched rule in the client connection log first, then verify the exit region. If local websites are sent through an international route, narrow the proxy rules. If a target international service is incorrectly connected directly, check the domain rules, process rules, and final fallback policy.

Client capabilities also vary by platform. Windows and macOS clients can usually manage the system proxy or a virtual network interface. iOS and Android are affected by the system VPN interface, background execution, and battery-saving policies. Linux clients may depend more on the command line, desktop proxy settings, or routing rules. After importing the same subscription, confirm the connection mode and DNS settings separately on each platform.

Refund Requests and Required Details

Question 10: How do I request a refund, and what should I check first?

VPNKF offers a 7-day, no-questions-asked refund. To request one, submit a support ticket through the user dashboard within the applicable period and provide information that can identify the order. When describing the issue, include the platform, client, selected route, symptoms, and troubleshooting already completed. This makes the situation easier to assess than simply writing “it doesn’t work.”

If the issue involves a subscription that has not updated, an incompatible client, or incorrect split-tunneling settings, you can first follow the checks below. Troubleshooting does not affect your right to request a refund under the refund terms, while complete details can reduce back-and-forth clarification.

  1. Confirm that the local network can access ordinary websites normally with the proxy disconnected.
  2. Return to the user dashboard and check the subscription status and remaining data.
  3. Update the subscription and confirm that the client supports the protocol used by the route.
  4. Switch between different route types and record the exact error or relevant log keywords.
  5. If the issue remains unresolved, describe the order and usage environment in a dashboard ticket and request a refund or technical support.

When using the service for the first time, keep your dashboard order details and client error logs, but do not paste the full subscription link on a public page. A subscription link is sensitive credential information and should only be handled through the site’s support channel when submitting a ticket.

Final assessment: Check the subscription, client, local network, and target service separately. Multiple devices share data, changing routes changes the exit, protocol performance depends on the network environment, and DNS and split tunneling require separate verification. If the service does not meet your needs, request a refund under the 7-day, no-questions-asked refund terms.
