Step-by-step solutions
Test mobile data without Wi-Fi
Keep your plan’s data allowance in mind.
Find mobile data in Android Settings; names vary by manufacturer. Confirm it is enabled.
To separate connections, temporarily turn Wi-Fi off, toggle mobile data off and on, and test a small page. Restore Wi-Fi afterward if needed.
Observe the indicator and compare results
Do not infer a fault from one app alone.
Look for a cellular data indicator beside the signal. If absent, check coverage at your location and contact the carrier.
If present but browsing fails, try another app. If none works over mobile data, give the carrier the indicator and Wi-Fi-off test result to investigate the line or service.
Still not working?
Record what works over Wi-Fi and mobile data, the indicator and the general location of the failure. Ask the carrier to check coverage and account state before editing APNs or resetting settings without specific guidance.
