How Does SIM Card & Internet Work in China?
Last verified: 2025-06 · Asia
1The Quick Answer
Buy a local SIM at the airport from China Mobile, China Unicom, or China Telecom — but install and configure your VPN before you land, as local SIMs are subject to the Great Firewall.
2What You Need to Know
China's three main carriers — China Mobile, China Unicom, and China Telecom — sell tourist SIM cards at major international airports and carrier stores; bring your passport. Local SIM data is fast and cheap but is subject to the Great Firewall, meaning Google, WhatsApp, Instagram, and most Western services are blocked without a VPN. International roaming on your home SIM is generally not blocked by the Great Firewall, making it a possible alternative for light internet use, though it is expensive. A VPN must be downloaded and configured before arriving in China — the Great Firewall blocks VPN app stores and download pages.
3Practical Tips
Practical Tips
- 1Install, subscribe to, and test your VPN app at home before your flight — once inside China, you cannot easily download or activate a new VPN.
- 2China Unicom and China Telecom tourist SIMs are available at Beijing Capital, Shanghai Pudong, and other major international airports immediately after customs.
- 3Pocket Wi-Fi (portable hotspot) devices can be rented at airports and often come with data that is pre-configured for the Great Firewall environment — confirm before renting.
Important Warning
If you do not set up a VPN before landing, you will be unable to use Google Maps, WhatsApp, Gmail, Instagram, YouTube, or most Western apps for your entire trip — this is a critical preparation step.
