AT&T USA | Internet not working | Fix by custom APN

If the AT&T Mobile internet is not working on your cellphone, it can be fixed easily by adding an APN configuration. You can read this at my Reddit as well. Go to Settings -> Connections -> Mobile networks -> Access Point Names; Edit an existing APN configuration or create a new one. Save and activate. An iPhone settings is mostly at Settings > Cellular > Cellular Data Options > Cellular Network OR Settings > Mobile Data > Mobile Data Options > Mobile Data Network.
