You have two realistic options as a tourist: an eSIM you buy before departure, or a physical SIM card from a counter after you land. Both give you mobile data. The difference is when it starts working and how much standing in line is involved.
The short answer: if your phone supports eSIM, buy one before you fly. It activates when you land, which means you walk off the plane with working maps and a working translator instead of hunting for airport wifi.
Whichever you choose, don't stop there. The most reliable internet strategy for China is assuming you'll sometimes have none — more on that below.
An eSIM is a digital SIM you install by scanning a QR code — no plastic, no counter. You buy a China data plan online, install it at home over wifi, and switch it on when your plane touches down.
Two things to check before paying. First, your phone must support eSIM — most recent iPhones and flagship Androids do, but confirm in your settings. Second, your phone must be unlocked; a phone locked to your home carrier can refuse a foreign plan.
Most travel eSIMs for China route your data through international roaming. In practice that often means your usual apps keep working on mobile data even when they wouldn't on a local network — but providers change their setups, so read recent reviews of any provider close to your travel dates.

Bring your passport. As of 2026, SIM cards in China are registered to a real identity, so the clerk will scan or photograph your passport as part of the sale — this is standard procedure, not a scam. Budget some time, especially if a full flight landed just before yours.
Counters may keep limited hours, so a late-night arrival can mean no SIM until morning — one more argument for the offline preparation below. For everything else between the plane and the taxi, see the airport arrival guide.
Almost every hotel that takes foreign guests offers free wifi, and in cities it's generally fast enough for video calls. Ask for the password at check-in — reception staff answer this question a dozen times a day.
One thing travelers miss: hotel wifi is still a Chinese network. Apps and websites that don't load on a local SIM won't load on hotel wifi either, no matter how strong the signal is.
Here's the honest part most eSIM ads skip: internet access in China can be unpredictable for visitors. Some foreign apps and sites are unreachable on local networks, roaming setups change, and rules shift without notice. Treat any specific "this app works, that one doesn't" claim as perishable and verify it shortly before you fly.
The fix is not a better SIM. It's making sure the tools you'll actually need — maps, translation, key phrases, booking details — work with no connection at all. A phone that's useful offline turns every network problem from a crisis into a shrug.
The apps for your China trip guide covers what to install; the checklist below covers what to download into those apps before you board.
Do all of this at home, on fast wifi, at least a day before departure:
Some travelers also set up a VPN before departure. If that's part of your plan, configure and test it at home — sorting it out after you arrive is much harder.
If your phone is unlocked and supports eSIM, buy an eSIM before departure — it activates when you land. If not, buy a physical SIM at an airport carrier counter after arrival and bring your passport, since real-name registration requires it as of 2026.
Hotel wifi is a Chinese network, so anything that won't load on a local SIM won't load there either. Access rules change, so verify close to your trip — and download offline maps, translation packs and a phrasebook before you fly.
Yes. As of 2026, SIM cards in China are registered to a real identity, so the counter staff will scan your passport as part of the sale. It's standard procedure, not a scam.
Offline maps for every city on your route, offline translation language packs, an offline audio phrasebook, and screenshots of your bookings with addresses in Chinese characters. Do it all at home on fast wifi.
