For your device to connect to the Internet, make sure:
It has at least two signal bars. If it doesn't, your signal is too low for reliable data speeds. Check out Signal issues / no service troubleshooting instead.
It displays a data service icon (3G, 4G, or LTE). If not, see No icon for 3G, 4G, or LTE.
It has coverage in your current location. Buildings can impact data signal or speed. If you're inside, move outside to check for improvement.
If your device meets the criteria above, but still won't connect to the Internet, proceed with the troubleshooting steps below.
