VPN basics and how to choose oneWhat is a VPN?
Why you need one in mainland China.
A one-page guide to how a VPN works, what people use it for, how free and paid VPNs differ, and what to look for when you choose one. At the end, a little about us: VPNKING.
What is a VPN
What is a VPN?
A VPN (virtual private network) creates an encrypted tunnel between your device and a VPN server. Your internet traffic goes through that server first, then on to the site you're visiting. To the website, the connection comes from the VPN server's IP address, not the one where you are. To other people on the same Wi-Fi, all they see is encrypted data.
That's why people mostly use a VPN for two things. One is going online from somewhere else, for example through a server in Taiwan while you're in mainland China. The other is protecting your connection, so people on a public network can't see what you're doing.
Why you need one
Why do you need a VPN in mainland China?
Google, LINE, Facebook, Instagram, YouTube and many other services from outside mainland China don't work on mainland China networks. If you travel, work, study or live there and want to message family and friends back home on LINE, search on Google or watch YouTube, you need a VPN that connects you to a server outside mainland China.
Traditional VPN connections tend to be unstable on mainland China networks: they often fail to connect or work only on and off. Most VPN services for mainland China now use newer connection methods that hold up better there. VPNKING does the same, and every subscription includes two lines, so if one isn't working well you can switch to the other.
What it's for
Common uses for a VPN
Using overseas services in mainland China
LINE, Google, Gmail, Facebook, Instagram and YouTube don't work in mainland China. Connecting to a server outside the mainland through a VPN lets you use them normally.
Extra protection on public Wi-Fi
In cafes, airports and hotels, the connection between your device and the VPN server is encrypted, so others on the same network can't see what you send.
Going online with a Taiwan IP
Some websites and services only work with a Taiwan IP. Going online through a Taiwan server lets you connect as if you were in Taiwan (each platform has its own rules, so we can't promise every service will work).
Working while you travel or stay abroad
Check Gmail, open Google Docs and hold video meetings on LINE, so work and keeping in touch carry on as normal.
Free vs paid
How are free and paid VPNs different?
Four things to check when choosing
- 1
Does it suit mainland China networks?
Traditional VPN connections tend to be unstable on mainland China networks and drop often. Look for a service built for those networks, ideally with a backup line you can switch to.
- 2
Is there a trial or a refund?
Your experience depends on your mobile carrier and the city you're in. Being able to try it first, or a clear refund policy, makes it less likely you'll buy the wrong thing.
- 3
Can you reach a real person?
Setup is where people get stuck most often. Real people on support who reply in a language you can use, plus complete illustrated guides, mean you're not on your own when something goes wrong.
- 4
Are the terms clear?
The clearer the rules on data, devices, expiry and refunds, the better. Be careful with numbers that promise too much.
About us
About VPNKING
VPNKING has provided VPN service for mainland China since 2020. From the start, it has been built around real people answering on LINE and helping each customer set up one-on-one.
In 2026 we rebuilt the whole service: upgraded connection methods, automatic activation once payment is complete, and rewritten guides for iPhone, Android, Windows and macOS. We also started offering a free 1-day trial.
