Understand the journey
What this looks like on a real trip
Mobile data is the bridge between the airport and the rest of your trip: your hotel address, map pin, translation, ride pickup and payment setup may all depend on it.
Choose roaming, a travel eSIM or a local SIM by checking your own device and provider. Some overseas online services are restricted on mainland networks; what works on roaming or an eSIM depends on how that provider routes traffic. Save the first day's essentials offline regardless.

The short answer
How do I get mobile data and use the apps I need?
Choose a data plan before departure, confirm it works in mainland China, and keep your first hotel address and key bookings offline. International roaming or a travel eSIM may be simplest for a short stay; a local SIM is another option and usually needs your passport. Which online services work depends on the network and plan, so test the services you rely on before travel.
See Beijing's local SIM guideBefore you go
- Check phone unlocking, eSIM support, mainland coverage, data allowance and activation instructions with your provider.
- Keep your original phone number available for bank, booking and app verification messages.
- Install a China-capable map, translation, payment and ride-hailing app before you arrive.
- Save an offline copy of your hotel name and address in Chinese, arrival transfer and reservation confirmations.
Choose the relevant path
Which situation fits your trip?
Short trip, simplest setup
- If
- Your existing carrier offers mainland roaming at an acceptable price and your usual number must receive bank codes.
- Do this
- Confirm roaming coverage, data price and activation timing; keep your home SIM active and test mobile data before leaving the airport.
- Watch for
- Roaming rules for mainland China may differ from Hong Kong or Macao. A 'China' plan should name mainland coverage explicitly.
Data-first travel eSIM
- If
- Your phone is unlocked and supports eSIM, and you can keep your home number separately for SMS.
- Do this
- Check the plan's mainland coverage, validity start, data allowance, activation method and whether it is data-only.
- Watch for
- A data-only eSIM does not give you a mainland phone number; some apps still need verification to your original number.
Local number or longer stay
- If
- You need a mainland number or a local plan for more data or time.
- Do this
- Visit a carrier-operated service hall or an official airport service point with your passport and compare plan terms.
- Watch for
- The Beijing government's SIM process requires passport identity registration; opening hours and outlet services vary.

Practical playbooks
01
Prepare an offline arrival pack
Build this before departure, even if you bought an eSIM.
- 1.Screenshot the hotel confirmation with Chinese name, street address and phone number; save the map pin and your airport transfer plan.
- 2.Save flight and rail booking references, passport details needed for check-in, the travel-insurance number and embassy contact in a secure offline place.
- 3.Install the map, translator, payment and ride-hailing apps you will actually use. Sign in while your home SMS service is working.
- 4.Download the translator's offline language pack if the app offers it. Check whether your maps and saved places are available without data.
02
Get connected after landing
Do this before leaving the airport if possible.
- 1.Turn on your chosen data line and confirm that mobile data is assigned to it. If using two SIMs, keep the home line available for bank or app codes unless roaming charges make this unsuitable.
- 2.Open a normal web page and your payment/map apps. Do not use the first taxi ride as your connectivity test.
- 3.If you need a Beijing local SIM, follow signs to an official 'Beijing Service' counter or carrier outlet at PEK or PKX and show your passport.
- 4.Ask staff to confirm the plan's data, voice/SMS, duration, top-up method and whether you can receive registration codes before paying.
03
Handle an app that does not work
Use this when a familiar overseas service or new account fails in China.
- 1.Determine whether the problem is mobile data, the specific app, a missing SMS code or an account identity check. Test one ordinary website first.
- 2.Do not rely on Google, Facebook, YouTube or X on a mainland connection; UK government travel advice lists them as blocked. Service access can vary with the network and change over time.
- 3.Switch to the tool that covers the actual task: a saved Chinese address and staffed taxi counter for transport, a physical card or cash for payment, or your printed booking for hotel check-in.
- 4.For a blocked or unavailable service, use its official support or an available local alternative; do not install an unknown app from a QR code handed to you by a stranger.
- 5.At a hotel, ask for help with Wi-Fi only after confirming its network name with reception.
More practical detail
Set up these apps before you fly
Install and sign in while your home number can receive verification codes. Cover these four jobs.
- Maps
- Use a China-capable map and save your hotel, station and first-attraction pins. Test whether your usual map works on a mainland connection.
- Translation
- Install a translator with camera and offline support, then download the Chinese pack before departure.
- Payments
- Set up Alipay or WeChat Pay with an eligible card and a second method. Complete identity checks before you leave home.
- Ride-hailing and rail
- Didi covers city rides and 12306 handles trains. Some venue mini-programs ask for a mainland number; a hotel can sometimes help with booking.
Show this when words are difficult
Save the relevant line with your address or booking. Show the Chinese text to staff rather than relying on pronunciation.
At a carrier counter
我想办理可以上网的手机卡，需要保留短信功能。
I would like a mobile data plan and need SMS service.
Ask for Wi-Fi
请问这里的官方 Wi-Fi 名称是什么？
What is the official Wi-Fi network name here?
If things go wrong
- If mobile data does not activate, connect to a trusted airport or hotel Wi-Fi network, follow your provider's activation steps, or visit an operator desk with your passport.
- If an app cannot send a code to your number, use the service's official support path; use your saved Chinese address and a staffed transport option to reach your hotel.
Common questions
Do I need a Chinese phone number?
Not for every short trip. Many visitor services support overseas numbers, but individual app features can differ. Verify your essential apps before departure.
Can I buy a local SIM at the airport?
At some airports, yes. Beijing's official guide lists airport counters and operator halls; bring your passport and check the local airport's current hours.
Will Google Maps work in China?
Do not rely on it on a mainland connection. Google services are blocked there, and access depends on your network or roaming provider. Install a China-capable map and save offline pins before you fly.
