Check network coverage

You can experience AT&T cellular data not working if your area has poor AT&T coverage. Therefore, you should check the network signals in your area and try moving to a location with better AT&T coverage.

Reinsert your SIM card

You can try removing and inserting your SIM card into your device because improper placement of SIM can restrict your signals and cause AT&T cellular data connectivity issues.

Check your data plan

You can check whether you have consumed your data limit for your subscribed AT&T plan. If you have exhausted your data, you won’t be able to use the Internet even with your mobile data turned on.

Check storage

The other fix you can try is to check your storage. If your device’s storage is full, you should free some space by deleting unnecessary folders and files or clearing the cache.

Reboot your Device

Therefore, you should check the wifi feature and ensure it is turned off when your phone is connected to AT&T cellular data.

Authentication Type
APN Type
default, mms, supl, hipri
APN Protocol IPv4
