A China eSIM with no internet may be installed and registered while the wrong data line, roaming setting, exhausted allowance or APN prevents traffic. App availability is a separate question from whether mobile data works.
Test a simple webpage and map before assuming every service should behave identically in mainland China.
NoveSIM travel eSIMs are data-only, so ordinary carrier calls and SMS are not connection tests.
Quick answer: Select the China eSIM for Mobile Data, enable Data Roaming, disable automatic switching and check the plan balance. Toggle Airplane Mode, leave Network Selection on Automatic and use data.esim only if manual APN entry is required.

Confirm Whether All Internet Is Failing
Turn Wi-Fi off and try two unrelated websites. If some services work but one app does not, the mobile connection is active and the issue may involve that service, account or local availability.
Run the Safe Connection Sequence
- Confirm the eSIM is enabled.
- Select it for Mobile Data.
- Enable roaming on it.
- Keep primary-line roaming off.
- Disable automatic data switching.
- Toggle Airplane Mode for 30 seconds and retry.
The China activation guide covers the initial settings.
Check Plan Status and Location
Verify remaining data, validity and that mainland China is included. Hong Kong and Macau may be separate destinations. Test outdoors or in a second location to rule out indoor coverage.
Review the live China eSIM plans for current partner and coverage terms.
Network Selection and APN
Begin with Automatic Network Selection. Test only a carrier authorised for the plan. If manual APN entry is required, use data.esim with blank username and password.
The China APN guide explains where to enter it.
Contact Support
Send the order number, city, exact phone model, balance, selected network and safe screenshots. Do not publish the QR code.
Keep the installed eSIM and delete it only if NoveSIM Support specifically instructs you.
