Where and how to buy a Chinese SIM card as a foreigner: major carriers, documents, eSIM, plans, and top-ups.
A local Chinese SIM card is one of the first things you should sort out after arriving — almost every app you will rely on, from maps and ride-hailing to Alipay and WeChat Pay, needs a working Chinese phone number. This guide covers where to buy a SIM, what documents to bring, eSIM options, and how to top up.
At a glance
Quick answer
Buy your SIM from an official carrier store — China Mobile, China Unicom or China Telecom — rather than a street kiosk. Real-name registration with your passport is mandatory and only licensed counters can complete it. Have the staff insert the card, activate data and test it before you leave the counter. A travel eSIM is fine for the first day or two, but you still need a mainland number for Alipay, WeChat Pay, delivery and most app logins.
Check the official source before you act
This guide reflects rules and prices as published by Chinese authorities and providers, and was last reviewed in September 2026. Rules, fees, platform features and deadlines change, and city offices and branches apply them differently. Confirm the current position with the carrier’s official store or hotline (China Mobile 10086, China Unicom 10010, China Telecom 10000) before you rely on any figure below.

China’s big three all offer foreigner-friendly plans:
Any of the three works fine in major university cities. Pick based on a friend’s recommendation or which has a branch near campus.
Avoid street vendors and unofficial stalls offering ‘no documents needed’ deals — they can be scams or resell recycled numbers.
If your phone supports eSIM (most recent iPhones and many Android flagships), some carriers — notably China Unicom — offer eSIM profiles for foreigners. The upside is no physical card swap. Real-name registration is still mandatory, so you still register with your passport at a store or through the carrier’s app. Check compatibility with your device maker before relying on this.
About these prices: plan prices, data allowances and eSIM availability change often and differ by province and by store. Treat the numbers below as typical ranges and check the current packages in the carrier’s app or at an official store.
Recharge through the carrier’s own app, or more easily via Alipay or WeChat Pay (search the carrier name in the app). You can also top up at any carrier store or convenience store kiosk. Set a calendar reminder so you never run out of data before a trip.
A Chinese SIM card can be suspended if it is unused for several months, if the real-name registration details do not match your passport, or after a lost-phone report. If your card suddenly shows no service, visit any company-owned branch of your carrier with your passport — they can reactivate the number on the spot in most cases, which matters because your WeChat, bank and Alipay accounts are all linked to that phone number. For a short trip, a China Unicom or China Telecom prepaid travel SIM with a set validity period avoids the problem entirely: it simply expires instead of being suspended, and you buy a fresh one next visit.

Most phones sold outside China take one physical SIM plus an eSIM, and Asia-market models often take two physical SIMs. Keeping your home number active means you still receive bank codes and two-factor logins from home — but roaming charges add up fast, so switch data over to your China SIM and turn roaming off on the other line.
Keep the China number alive even during long holidays. Banks, delivery apps and police registration all send verification codes to it, and recovering a cancelled number means a trip back to a carrier store with your passport.
