Stable routes for cross-border work, AI Tools, and streaming access. 110+ countries / 210+ routes, from ¥9.9/month.
The cross-border connection experience depends on more than a single node. Entry routing, link type, protocol handling, and exit region must work together to reduce route switching and repeated troubleshooting.
During peak hours, the main issue is often not device performance but the combined effect of congested entry points, detours across regions, and pressure at exit points. C4VPN distributes connection requests across multi-region entry points and different route types, so users can change paths based on their network and target service. If pages load slowly or long-lived connections drop, switch routes within the same region first, then compare nearby regions. Route organization emphasizes choice instead of forcing every use case onto one shared path.
Public networks, shared office networks, and temporary access environments pass through more intermediary links, so connection protection needs to cover transmission from the device to the service entry point. C4VPN uses quantum encryption as a core security mechanism and handles route authentication by connection session. Keep your username, password, and subscription details secure; no extra information needs to be entered repeatedly across clients. Security is built into the connection flow without requiring complex parameters or sacrificing everyday convenience.
Work computers, personal computers, tablets, and mobile devices often handle different tasks at the same time, while splitting plans by device adds management overhead. C4VPN plans support unlimited devices, and Windows, macOS, iOS, Android, and Linux can use the subscription under one account. When changing devices, retrieve the C4VPN client and subscription again from the dashboard instead of creating a separate account. This suits individuals, developers, and small teams switching between multiple operating systems.
AI coding, web-based conversations, and command-line tools depend on continuous requests. Brief interruptions can lose context, trigger retries, or stop terminal tasks. C4VPN offers routes across Asia, North America, and Europe, making it easier to match an exit region to the tool's location. For development, prioritize shorter paths with more stable persistent connections, and configure browser and command-line usage separately. The goal is to reduce repeated reconnections during long sessions, not chase a momentary speed-test number.
Streaming services display different libraries based on exit region, account region, and content rights, so confirm the content region you need before choosing a route. C4VPN marks streaming support on node previews and route pages. Filter by country or region first, then choose a city. If quality drops during playback, keep the same region and switch to another route to avoid triggering regional re-identification. Route labels shorten the trial-and-selection process but do not replace the platform's own account rules.
Network conditions vary with the access provider, location, operating system, and target service, so public information cannot reflect every user's situation. C4VPN offers a 7-day no-questions-asked refund, allowing testing on everyday devices, common time periods, and primary use cases. Check login, client retrieval, route switching, regular browsing, and long-lived tasks in sequence, while keeping relevant environment details if an issue occurs. If the service is not suitable, submit a request under the refund policy.
C4VPN covers 110+ countries / 210+ routes. The list below shows route-selection patterns for commonly used regions; the full page includes more countries, cities, and route types. Choose an exit region matching the target service, then compare routes for cross-border work, development tools, or streaming. This is more likely to produce a stable result than connecting at random.
| Country or region | City | Route type | Streaming |
|---|---|---|---|
| Asia | |||
| Hong Kong, China | Hong Kong | IEPL dedicated line | Supported |
| Japan | Tokyo | Transit route | Supported |
| Singapore | Singapore | IEPL dedicated line | Supported |
| North America and Europe | |||
| United States | Los Angeles | Transit route | Supported |
| United States | San Jose | Direct route | Supported |
| Germany | Frankfurt | Transit route | Supported |
For services in Asia, start by checking Hong Kong, Tokyo, and Singapore. For North American services, try Los Angeles or San Jose; European office systems can use regions such as Frankfurt. IEPL dedicated lines suit tasks that prioritize peak-hour stability, transit routes balance coverage and connection quality, and direct routes work well when the network path is already smooth. No route fits every access network, so keeping nearby regions as alternatives is more practical.
The latency and bandwidth figures below are supplied by the site's route component for quick comparison within the current list; they are not an uptime guarantee. Static route coverage and live status are shown separately so short-term changes do not become part of long-term service claims.
All monthly subscriptions reset their data each month on the activation date. When upgrading mid-cycle, the price difference is prorated for the remaining days. All three plans share the same platform support, quantum encryption, and unlimited-device rules; the main difference is the monthly data allowance.
60GB per month, reset on the activation date.
Best for light use focused on browsing, email, document collaboration, and occasional AI Tools. If most activity takes place during work hours with little extended HD streaming, this tier makes recurring costs easier to control.
250GB per month, reset on the activation date.
A good fit for daily cross-border work systems, AI coding tools, cloud collaboration, and streaming. The allowance supports more continuous connections and switching between computers, tablets, and mobile devices.
500GB per month, reset on the activation date.
Designed for extended online sessions, HD video, larger file transfers, and continuous connections across multiple devices. If monthly usage varies considerably, the higher allowance reduces the need to check remaining data frequently before reset.
Whether a subscription service suits long-term use depends on more than price. Before paying, users should be able to find what account details are required, how routes are chosen, how devices are managed, when data resets, and what to do if the service is not suitable.
Create an account with only a username and password. Fewer account details to enter and maintain make it faster to test a route. Keep your username, password, and subscription details secure, and never share subscription contents in public chats, screenshots, or shared documents. When changing devices, retrieve the C4VPN client and subscription again from the dashboard.
Coverage, prices, refund rules, and device rules are fixed service information. Route latency and bandwidth change with the current network, so they are shown only by the live component. This provides a useful reference when comparing routes without turning short-term test results into long-term promises.
The node page lists cities, route types, and streaming support by region. The technical reference page further explains the trade-offs between direct, transit, and dedicated routes. Everyday users can choose quickly by region, while advanced users can explore protocols, packet loss, and the causes of peak-hour congestion.
The main difference between monthly subscriptions is the monthly data allowance. Platform support, unlimited devices, quantum encryption, and refund rules do not change by tier. Choose a monthly subscription for steady usage, or compare non-expiring data bundles for variable usage without having to understand complex discount combinations first.
These answers cover accounts, devices, data, route selection, and refunds. For connection issues, client imports, and billing details, visit the Help Center for categorized guidance.
Open Help Center →No email address is required; a username and password are enough. Use a password that is difficult to guess and store your account details separately. After creating the account, choose a plan and retrieve the C4VPN client and subscription information from the dashboard.
Windows, macOS, iOS, Android, and Linux are supported, with unlimited devices. Client retrieval may vary by operating system; use the download entry in the dashboard to avoid installers from unknown sources.
Monthly subscription data resets each month on the activation date. If the current tier is not enough, you can upgrade mid-cycle and have the price difference prorated for the remaining days. Data bundles remain available until depleted and never expire.
Keep the target region unchanged and switch to another route within that area first. If the result is still unsatisfactory, compare nearby regions. For work and AI Tools, prioritize stable long-lived connections; for streaming, first confirm the region support shown on the route page.
C4VPN provides a 7-day no-questions-asked refund. Test on your usual devices, networks, and primary usage periods, then review the refund policy for the submission process before applying.
