| What to check | Travel eSIM | Home-carrier roaming | Local SIM |
|---|---|---|---|
| Before arrival | Often install in advance | Activate with your carrier | Check available purchase options |
| Phone compatibility | Unlocked + supported eSIM | Carrier and plan dependent | Unlocked + supported network |
| Chinese phone number | Often data only; check plan | Usually keeps home number | Check with the operator |
| Useful when | You mainly need mobile data | You want to keep your existing setup | You need a local number or longer service |
Mainland networks restrict access to some overseas sites and apps. Access also depends on your provider. Confirm essential services before relying on them; no option here guarantees access to every app.

Three quick checks. Compare the provider’s terms before buying.
Your connection checklist
- Check your exact phone modelConfirm eSIM support, carrier unlock status and compatibility with the plan seller. Do this before paying.
- Read activation and expiry rulesSome plans start on installation, others when connected. Keep the provider’s instructions and support details offline.
- Keep verification messages availableAsk your home carrier how SMS works abroad. Avoid accidental data roaming charges on the wrong line.
- At arrival, test the right data lineSelect the intended SIM for mobile data and follow its roaming/APN instructions. Do not delete an eSIM while troubleshooting unless your provider tells you to.
- If nothing connectsUse a staffed airport help desk or official telecom shop. Bring your passport for a local SIM registration. Do not rely on public Wi-Fi always being available.
Save these offline: hotel name and address in Chinese, booking confirmations, airport transfer, insurer and embassy contacts.
