You'll need mobile data almost all the time in China — to pay, to call a taxi, to open a metro QR code. Pick one of these three options before you go.
| Option | Good for | Things to know |
|---|---|---|
| Travel eSIM (bought online before you fly) | Short trips; anyone who wants data on arrival | Data only, usually no Chinese phone number. Install it at home, switch it on when you land. Your phone must support eSIM. |
| Chinese SIM card (bought in China) | Longer stays; anyone who needs a Chinese number | Sold at carrier counters (China Mobile, China Unicom, China Telecom), including at major airports. You must show your passport — every Chinese number is registered to a real name. |
| Roaming on your home plan | Very short trips; business travellers on a company plan | Simplest set-up, but check your carrier's daily price and data allowance for China before you go. |
Why a Chinese phone number can help
Some apps and services work better with a Chinese (+86) number — for example certain deliveries, some mini-programs and booking platforms. Many travellers manage fine without one; if you're staying several weeks, it's worth having.
