China is the destination where the choice of eSIM changes what you can reach online. Local networks block many familiar apps and sites, and some travel eSIMs route data differently, so check how a plan works before you buy.
Mobile networks in China
The main networks are listed below. A travel eSIM connects to one of them or to a partner, and the provider decides which, so the network named in the plan details is worth a look if coverage matters on your route.
SIM rules and ID for visitors
Real-name registration is mandatory for local SIM activation, and a passport is the usual document, sometimes with in-person checks and facial recognition. A foreign travel eSIM bought before the trip is a separate route.
Rules change
Registration and phone rules are updated by governments and operators without much notice. Check the current position with the operator or the provider before you travel.
Using a travel eSIM in China
Blocked services
Services such as Google, Instagram, WhatsApp and Telegram are blocked on local Chinese carrier connections.
Data routing matters
Some international travel eSIMs route data outside mainland China, which can give access to blocked services. This depends on the provider and plan, so check the routing before you buy.
Data only
Most travel eSIMs are data only with no Chinese number. Keep your home SIM active for SMS and one-time codes.
Buy before arrival
Some sellers cannot sell plans from inside mainland China, so buy and install before you fly.
Check before you fly
- The plan's data routing, since claims differ between vendors.
- A way to get one-time codes: keep the home SIM active.
- Offline maps and a payment method that works locally.
- You have installed the eSIM on Wi-Fi and know how to switch the line on when you land. The guide on when to buy and install covers the timing.
Which plan fits a trip to China
A China plan or a regional Asia plan can both work, but read how each routes data, because that decides which apps you can use. The destination guides page explains the difference between local, regional and global plans, and our multi-country guide walks through route choices.
