Hi everyone! :grin:

This may seem quite simple, but many beginner Android users are having trouble with this.

To be able to take advantage of the 4G network, you need to activate the 4G settings beforehand. Here are the steps:

Once you are on the home screen of your device, tap on the settings button.
Next select More settings.
Then go to Mobile networks and select Network mode.
Here check the box for LTE/GSM/WCDMA (auto-mode).

Now your 4G network has been activated!

Do you have any further questions or problems?

I can't find the network mode option on my daughter's phone. It's att and it is an unlocked phone.

Hey Paola,

Do you mean that "network mode" is not listed in the "mobile networks" section??
