A travel eSIM is usually the simplest option for a short trip: install it before departure, activate on arrival and keep your home SIM for bank codes. Local SIMs can be cheaper for long stays but require passport registration. Hotel Wi-Fi is common but does not guarantee access to every service.
This is practical guidance, not legal advice. Entry and payment rules change. We confirm the current rule for your passport and route in writing before you book.
eSIM vs local SIM vs roaming
An eSIM avoids a shop visit and lets you keep your home number active for bank authentication. A local SIM can be better value for a longer stay, but you need an unlocked phone and passport registration. Your home carrier's roaming may be the easiest option for a short trip, but check the daily price before you rely on it.
If your phone supports dual SIM or eSIM, use the travel data line for maps and the home line for SMS codes. Test the setup before you leave home.
Apps and access
Some international services are restricted in mainland China, and rules can change. Do not assume that every app you use at home will work. Install maps, translation, payment and messaging apps before you fly, and download offline maps and language packs.
We send a short app checklist and set up a group chat with your guide. Your guide is your human backup when an app does not cooperate.
Wi-Fi and security
Hotels, cafes and airports usually have Wi-Fi, but speeds and login requirements vary. Avoid sensitive banking on public networks, use a reputable VPN only where permitted, and keep your phone charged for maps and payments.
Frequently asked questions
Will Google Maps work in China?
Google services can be restricted in mainland China. Download an offline map and a local map app before you travel; your guide can also share locations and directions.
Can I use WhatsApp in China?
Access to some international messaging services can be restricted. Do not rely on one app for urgent contact; we share a local phone number and a WeChat contact before arrival.
Should I buy an eSIM before I fly?
For most short trips, yes — it is simpler than finding a shop after a long flight. Check that your phone is unlocked and that the plan covers mainland China.
