Staying Connected in China: Roaming, eSIM and Local SIM

By XOOTOUR Editorial Team · Updated 15 October 2026

A connection is your first travel tool after landing. The best option is the one your phone supports, that works where you are going and that still lets you receive your bank’s verification messages.

At a glance

• Check whether your phone supports eSIM and whether it is unlocked.
• Compare coverage and activation timing, not only the headline price.
• Keep your original number available for security codes.

1. Choose how you will connect

• Roaming is simple because it keeps your usual SIM. Ask your operator about mainland China coverage, data limits and charges before departure.
• For a travel eSIM, check phone compatibility, country coverage, activation date and whether the plan includes calls or data only.
• A local SIM is another option. China’s government guide says visitors can take a passport to a telecom operator’s service office to apply.

2. Set up before the airport rush

• Download installation instructions while you still have a dependable connection. Do not delete an eSIM profile unless the provider explains how to reinstall it.
• Keep access to the number attached to your bank and payment apps; a data-only plan does not necessarily receive its SMS codes.
• Save the hotel’s Chinese address, booking and airport route offline in case setup takes longer than expected.

3. Test the essentials on arrival

• Turn on the correct data line and check that maps, translation and your chosen payment app open as expected.
• If the connection fails, use official operator or provider support and airport Wi-Fi if available. Avoid entering passwords on an untrusted network.
• Once online, use XOOTOUR to refine your city route, then verify current transport and venue details separately.
