You can use the following solutions to fix AT&T cellular data not working.

Check the Airplane mode

Check for software updates

You must ensure your device software is up to date because outdated software can cause your AT&T cellular data not working. You should install the updated version if you are running your device on older software.

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

You can turn off AT&T’s free tablet or smartphone for a few minutes and then turn it on to establish the lost connection. Wait for a few seconds after you do this, and then check whether your AT&T cellular data is working.

Wifi Feature

Your AT&T cellular data may stop working if your wifi is turned on with the mobile data. This is because the smartphone can work with a wifi connection even when your cellular data is turned on, and the device gets confused between your wifi connection and cellular data when both are turned on.

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

Check your APN Settings

You can check whether your AT&T APN Settings are set to default. As mentioned, an incorrect APN Settings will not let you use your data. Otherwise, you can manually change your APN settings on Android or iPhone to fix connectivity issues.

Manually insert the following settings on your new profile.
