Frequently asked questions
Will a travel eSIM give me a Chinese phone number?
Most travel eSIMs are data-only and do not provide a mainland Chinese number. Check the plan details if an app or hotel may need local SMS or calls.
When should I install a China eSIM?
Install it while you have reliable internet, but follow the provider's activation instructions so the validity period does not begin too early.
How much data do I need for China?
Maps, translation and messaging use moderate data; video and hotspot use much more. Compare your trip length and normal daily usage rather than buying only by price.
