Arrange a way to communicate when you land, then choose a longer-term mobile plan once you understand your needs. Keep essential addresses and booking information offline so your first journey does not depend on a new account working immediately.
What should you check before leaving?
Ask your current provider whether your phone is unlocked, what roaming includes and whether you can receive verification texts abroad. Check your device's SIM capabilities before buying a service.
Download the information you will need for arrival: accommodation address, employer or host contact and your booking reference. Save important account-recovery methods somewhere you can reach without the same phone.
How do you get a local SIM?
Shanghai's official guidance describes purchasing and registering a SIM at an operator's store, with a passport for identification. It names China Mobile, China Unicom and China Telecom among the providers. Follow the official mobile-service guide for the current process.
Compare the plan before paying. Do not assume that a travel data product includes a local phone number or ordinary calls.
| Check | Why it matters |
|---|---|
| Data allowance | Navigation, calls and video use different amounts |
| Calls and texts | Some services need a reachable number or verification message |
| Renewal and minimum term | Know whether the plan renews automatically |
| Top-up method | Make sure you can keep the service active |
| Device compatibility | Check the exact phone and SIM arrangement |
| Cancellation | Understand what to do when you leave or change plans |
What about home internet?
Ask whether broadband is already included in a rental and whose account it uses. If you need a new connection, check installation timing, equipment, contract length and moving or cancellation terms.
Shanghai's home-internet guidance describes choosing a provider and bringing a passport when signing up. Test the connection for the tasks you need instead of judging it only by an advertised download speed.
Will your usual apps and websites work?
Do not make essential plans depend on untested access. Check your employer's required services, prepare offline teaching materials and agree a reliable way to reach people. Access can differ between services and connections.
For account security, use official app sources and keep recovery details current. Losing a phone can also interrupt payments, so keep an alternative way to reach your bank.
