International roaming in China is the easiest option for short trips because you can keep your existing SIM card and phone number. Before departure, check your carrier’s China roaming charges, data limits and mainland coverage.

A travel eSIM for China is a convenient mobile data option for international visitors with an unlocked, eSIM-compatible phone. Install your China eSIM before departure, confirm the data allowance and keep your original SIM active for verification messages.

A Chinese SIM card for tourists is useful for longer stays and travelers who need a local phone number. Passport registration is normally required, and some international websites may not be accessible through a mainland China mobile network.

Portable Wi-Fi in China allows several phones, tablets or laptops to share one mobile internet connection. It is a practical choice for families and groups, but you should check battery life, data limits, coverage, pickup and return arrangements.

• Avoid sensitive transactions on public Wi-Fi
• Use official venue networks, not random open hotspots
• Keep payment apps protected with a passcode
• Carry enough mobile data so you are never forced onto unknown Wi-Fi
