Yes, you can buy a local SIM at a China airport, and the one thing you must bring is your passport. Local Chinese SIM cards require real-name registration, and foreign visitors can register with a passport at carrier counters[1]. Expect a queue after a long flight, so plan around it.
If the counter signs look unreadable and you are tired, that is a common feeling. A little preparation makes it a ten-minute job instead of a stressful one.
What do you need at the counter?
Keep these in your hand luggage, not in a checked bag.
- Your original passport, the same one you used to enter.
- An unlocked phone, which your Malaysian telco can confirm in advance.
- A screenshot of the plan you want, with the data amount written in Chinese or English.
- Your hotel address in Chinese, in case you also need to ask for directions.
Staff scan the passport and take a photo of you to finish registration. This is normal, and it takes a few minutes per person. If you are a family, each adult registers a separate SIM.
How do you plan around the queue?
Treat the SIM as the second thing you do after landing, not the first. Download an offline map and save your hotel details before you fly, so you are never stuck while waiting.
Our guide to offline maps in China shows what to download. Save a bilingual hotel and transfer sheet too, so a taxi or driver can read your destination.
What will a local SIM not do?
It gives you Chinese mobile data, but it does not unblock the foreign apps. Google services, WhatsApp, Facebook, Instagram, X, Telegram and ChatGPT are blocked in mainland China[2].
So tell your family which app to use for messages, and decide whether you need a VPN. Any VPN has to be installed before arrival[3]. Read what works for WhatsApp and Google before you fly.
Is there an easier option?
Yes. An eSIM can be set up at home, with nothing to queue for. A roaming pass keeps your own number. Compare all three in our eSIM, roaming and local SIM guide, and see how telco passes compare.
Keep your Malaysian SIM safe in your wallet either way, because some bank codes still arrive there. When your phone is working, sort out the hotel side with our Wi-Fi and SMS guide. More preparation steps sit on the preparation topic page.
