Staying connected: roaming, local SIM, or travel eSIM

✅ Updated Jun 2026

You have three main ways to get mobile data in China. International roaming is the zero-setup option — your home number keeps working the moment you land, and as a bonus it often reaches blocked sites — but daily rates add up fast, so it suits short visits. A travel eSIM is the easiest middle ground: buy it online before you fly, activate by scanning a QR code, and you have data on arrival with no shop visit; some are routed overseas so they also reach blocked sites. A local SIM (China Mobile, China Unicom, or China Telecom) is the cheapest with the best coverage and is essential if you are staying a while — bring your passport to an official carrier shop, as real-name registration is required. For most newcomers the simplest plan is a travel eSIM for the first few days, then a local SIM once you are settled. You will need a working Chinese number to verify Alipay, WeChat, and most apps.
