TL;DR

Foreign visitors can buy a Chinese SIM card at airports, official carrier stores, or online via eSIM providers like Airalo, Holafly, and Nomad. SIM cards require passport registration. China Unicom is the best choice for foreign travelers — better English support, fewer restrictions. eSIM options work without a passport and can be activated before arrival. Expect to pay USD $10-30 for 7-15 days of data. A Chinese SIM unlocks full app functionality on apps that require a Chinese phone number (DiDi, Meituan).

Which carrier should I choose for a China SIM?

China Unicom is the best choice for foreign travelers — it has the most English-speaking staff, dedicated tourist plans, and the broadest international roaming partnerships. China Mobile has the largest network but the worst English support and may block some foreign apps. China Telecom sits in the middle. For a 1-2 week trip, Unicom is almost always the right pick.

Where can I buy a SIM card in China?

Official carrier stores in major airports (Beijing Capital, Shanghai Pudong, Guangzhou Baiyun) sell tourist SIMs at counters after customs — bring your passport. City-center carrier stores (look for the China Unicom blue logo) also sell SIMs, but staff may speak less English. Avoid buying SIMs from unofficial street vendors — they are often scams or have poor activation support.

Should I get an eSIM instead of a physical SIM?

eSIMs are increasingly popular for travelers because they activate before departure and skip the airport counter. Airalo, Holafly, and Nomad all offer China eSIMs (USD $10-25 for 5-15 days of data). However, eSIMs typically provide data only — they cannot receive SMS, which means apps requiring SMS verification (some banking apps, certain ride-hailing flows) will not work. For a smooth experience, get both: a physical SIM for full functionality and an eSIM as backup.

What data plan should I choose?

For most travelers, 10-20 GB over 7-15 days is sufficient. Video streaming and constant VPN use consume the most data. China Unicom offers a "China Travel SIM" package: ~¥99 for 7 days with 30 GB. Holaflo and Airalo sell 5-30 GB plans for USD $10-30. Always check the plan details for throttling policies — some plans drop to 1 Mbps after the first 3 GB.

Will my Chinese SIM work for apps like DiDi and WeChat?

Yes — a Chinese SIM unlocks the full local app ecosystem. DiDi (China's Uber) requires SMS verification, which a Chinese number provides. WeChat works fully with international numbers but works better and supports more features with a Chinese SIM. Meituan (food delivery, tickets) typically requires a Chinese number for payment binding.

Frequently asked questions

Can I buy a SIM card with just my passport?
Yes. Foreign visitors need only their passport to buy a SIM. Some carriers require a hotel address or local contact — Unicom's tourist plans do not.
How long does it take to activate a SIM?
Physical SIMs activate within 5-30 minutes after purchase. eSIMs activate instantly after scanning the QR code provided by the app.
Will a Chinese SIM work in Hong Kong and Macau?
Mainland Chinese SIMs typically do not work in Hong Kong or Macau without international roaming enabled. Buy a separate SIM or rely on WiFi in those regions.
Can I keep my WhatsApp number with a Chinese SIM?
Yes. WhatsApp works over data and does not depend on your phone number — your existing number continues to function. However, WhatsApp is often blocked in mainland China without a VPN.
What happens to my SIM if I extend my trip?
Most tourist SIMs can be topped up at carrier stores or via the carrier's official app (requires a Chinese payment method). Alternatively, buy a new SIM if your original expires.
