SweetAsSIMAbout this eSIM
Travelling to China mainland soon? Whether you're walking the Great Wall, exploring the Forbidden City, or wandering Shanghai's Bund, a China mainland eSIM gets your phone connected the moment you land - no roaming charges, no hunting for a local SIM shop, no swapping anything out of your phone.
In China mainland, it connects you via China Mobile (5G) and China Unicom (5G) and China Telecom (4G). Data runs at full network speed for maps, messaging and calls over Wi-Fi, and you keep your own number for texts and calls the whole time you're in China mainland. Buy online in minutes, install the eSIM before you fly, and it's ready to go from touchdown.

Almost certainly. Anything sold since 2019 is eSIM ready - dial *#06#, look for an EID, and you're good.

Most start the first moment your phone connects to a network at your destination, so it's fine to buy in January for a June trip and it'll sit there untouched until you land. A handful of plans instead start the moment you install the eSIM profile, so for those, install right before you fly rather than weeks ahead.
