Why does my android phone say no service when i have service

Contact your carrier to: Verify that your account is active and in good standing. Make sure that there are no outages in your area. Check that your device isn't blocked from receiving cellular services and is set up with the right data plan.

Sometimes, all you need to do when mobile data is on but no internet connection is to turn on and off Airplane mode. Doing so will cut off your phone from the mobile network and can fix the problem alongside it. On most Android devices, you'll find the Airplane mode toggle in the Quick Settings.
