eSIM vs Chinese SIM card vs roaming
Roaming and most travel eSIMs keep Google and WhatsApp working in China; a Chinese SIM gives a local number but needs passport registration.
Short answer: for most first-time visitors, a travel eSIM or home roaming is the better choice, because both usually route your data outside mainland China, so Google, WhatsApp and Instagram keep working. A Chinese SIM card is worth adding if you need a Chinese phone number, for example for food delivery or apps that want a local number, but it only reaches what’s accessible inside China and needs passport registration.

Check before you go: Plans, prices and data routing change. Before you buy a travel eSIM, confirm it covers mainland China and routes data outside China; before you rely on roaming, check your carrier’s China rates. The SIM chooser helps you compare.
Choose a travel eSIM if…
A travel eSIM suits most visitors to China who want foreign apps to keep working.
- Your phone supports eSIM and is carrier-unlocked.
- You want Google, WhatsApp, Instagram and your usual apps to behave as they do at home. Most travel eSIMs route data outside mainland China; read the plan to be sure.
- You want to keep your home SIM active for bank and card verification texts.
- You’d like to install everything before you fly and land already connected.
Choose a Chinese SIM card if…
A Chinese SIM card from China Mobile, China Unicom or China Telecom suits visitors who need to live like a local.
- You need a Chinese phone number, for food delivery riders, some apps and some public Wi-Fi logins. See How to order food delivery.
- You’re staying longer and want fast local data at local rates.
- You’re fine without blocked foreign services while on Chinese data.
Every Chinese SIM is real-name registered: you show your passport at the counter and the number is tied to you. Buy one at the carrier counters in airport arrivals or at a carrier store in the city.
Choose home roaming if…
Home roaming suits short trips and visitors who want zero setup.
- Your carrier’s China plan is affordable, or included in your plan.
- Your phone doesn’t support eSIM or isn’t unlocked.
- You want your foreign apps and home number working the moment you land.
Using an eSIM or roaming together with a Chinese SIM
On a dual-SIM phone you can combine options: keep a travel eSIM or roaming as your data line so foreign apps work, and add a Chinese SIM for its local number. Choose which line carries data in your phone’s settings. Hotel and café Wi-Fi in China are Chinese networks, so they behave like a Chinese SIM for blocked services. See Internet and apps for the full app setup.
