What happens if you try to use LINE in China
LINE cannot connect on Chinese networks — messages sit unsent, calls never ring, and nothing comes in. It has been blocked since 2014. This matters most for travelers from Japan, Taiwan, and Thailand, where LINE is the default way everyone communicates: your family group chat, your bookings, even your airline notifications may all live in an app that goes silent the moment you land.
What works
- LINE over a VPN
- LINE on international roaming data — traffic routes through your home carrier, outside the firewall
- Reading conversations already loaded on your phone
What doesn't work
- Sending or receiving messages on local wifi or Chinese SIMs
- Voice and video calls
- Timeline posts and stickers shop
- All LINE features without a workaround
Best alternatives in China
Do you need a VPN?
A VPN restores LINE completely. The easier route for most short trips: travelers from Japan, Taiwan, and Thailand usually keep their home SIM on data roaming, and LINE simply keeps working — roaming traffic exits through your home carrier, outside the firewall. Decide before you fly which route you are taking, and test it.
Common mistakes to avoid
- Not warning LINE contacts before the trip — tell your family group chat you may be slow to reply, or agree on a backup channel.
- Buying a Chinese SIM for cheap data without realizing it cuts off LINE — local SIMs sit behind the firewall, unlike roaming on your home SIM.
- Planning to install a VPN after arrival. App stores and VPN sites are blocked from inside China; prepare at home.
