Roaming

Keeps your home number and is often the lowest-friction first-hour data lane.

Check price, data cap and SMS behavior
Travel eSIM

Useful data without swapping a physical SIM. It usually does not provide a China phone number.

Check device and purchase-region support
Local SIM

Adds local data and a China number, but identity setup and app access behave differently.

Best when local SMS or calls matter
Wi-Fi

A fallback, not the primary plan. Hotel and venue networks can require SMS or portal sign-in.

Save an offline route before landing
This is a setup decision tool, not a provider ranking.

Pre-flight phone tests

If you land with no internet

Offline card

Stop debugging. Move.

Your first-hour fallback is not a better app. It is an offline route card.

If both data lanes fail → Show the Chinese address, use the official taxi rank or airport service counter, and fix phone setup after you reach the hotel.
