Set up a VPN before departure

Verify your phone is unlocked

Quick answer

For most visitors, an eSIM or prepaid SIM plus a VPN is the simplest way to stay online and access essential services.

If your phone supports eSIM, buy a plan before you travel so it activates on arrival. Otherwise, a prepaid SIM at the airport is a solid choice.

Check that your phone is unlocked and compatible with local bands. A quick test in advance prevents wasted time at the airport.

If you need access to blocked services, install and test a VPN before you fly. Some VPN websites are difficult to access inside China.

Have a backup VPN option and store activation codes offline in case you need to reinstall.

Hotels often require a phone number for Wi-Fi login. A local SIM makes this simple; without it, ask the front desk for access.

Public Wi-Fi is common but not always reliable. Use it as a backup, not your primary plan.
