Does eSIM Work in China?
Yes, eSIM works in China if installed and activated before you arrive, as new eSIMs cannot be purchased or installed in mainland China. International eSIMs provide data and WhatsApp access, but China's Great Firewall still blocks Google, Facebook, Instagram, X, and other restricted services.
Yes, an eSIM works in China as long as it is installed and activated before you land, since new eSIMs cannot be purchased or installed once you are already inside mainland China. This applies to both local and international eSIMs alike.
Does eSIM work in China the same way it does elsewhere?
Not entirely. China's internet operates behind the Great Firewall, a nationwide filtering system that blocks Google, Facebook, Instagram, X, and several other foreign platforms.
This restriction applies at the network level inside mainland China, so it affects any connection originating there, whether that is a local SIM (Subscriber Identity Module), a local eSIM, or an international travel eSIM.
Google Search, Gmail, and Google Maps stay blocked on Jetpac's China eSIM, the same as they would on any other connection inside the country.
WhatsApp is the exception here and keeps working on Jetpac's China eSIM even if your data pack runs out, so travelers can stay in touch with people back home without buying extra data first.
For ride-hailing, Didi is the app to download instead of Uber or Grab, since neither of those operates in mainland China.
If you need to actually call a hotel, taxi dispatcher, or local business, Jetpac's in-app calling reaches landlines and non-WhatsApp numbers in 50+ countries, so a local SIM isn't necessary just to make a phone call.
Does eSIM work in China regardless of which iPhone you own?
Not entirely, since where the phone itself was bought matters too. In mainland China, only two current iPhone models support eSIM at all, the iPhone Air and iPhone 17e, and even those require an in-person carrier visit with ID to activate.
Every other iPhone sold in mainland China has two physical SIM trays instead and cannot use eSIM technology in any form. Hong Kong and Macau support eSIM on a wider range of models, though still not all of them.
If your iPhone was bought outside mainland China, Hong Kong, or Macau, and it is unlocked and eSIM-compatible, Jetpac's eSIM will work on it normally.
So does eSIM work in China through a local carrier too?
Yes, but tourist access to local Chinese eSIMs is limited and usually requires identity verification at a carrier store, which is not practical for a short visit. A China eSIM skips that step entirely, since it is bought and installed digitally before you fly.
Local Chinese SIM/eSIM vs Jetpac's International eSIM
Setup: Local needs an in-store visit and ID. Jetpac installs digitally before departure.
Google access
Blocked either way, since the Great Firewall applies network-wide inside China.
WhatsApp access
Blocked locally without a VPN (Virtual Private Network). Works normally on Jetpac, even if your data pack runs out.
Purchase after arrival
Not available on either option, so buy before you fly.
Hotspot sharing
Rare on local plans. Unlimited on Jetpac.
How to Set Up Your eSIM Before You Land
Confirm your phone is unlocked and eSIM-compatible before departure, since this cannot be done once you are in China. After landing, turn the eSIM on under cellular or mobile data settings, enable data roaming for that line, and set it as your primary data line. It can take a few minutes to connect after you land.
So, does eSIM work in China for everything you need?
For data and WhatsApp, yes. For Google, no, whether or not you use a VPN. Jetpac also runs up to 70% cheaper than standard international roaming, so staying connected doesn't mean a surprise bill either way.
