Turning 4G on or off.
If our 4G network isn't available in your location yet, you can check our list to see if we're bringing 4G to your area.
You should also make sure that 4G is enabled on your phone. If for some reason you decide you don't want to use 4G yet, you can also disable 4G on your phone.
To enable or disable 4G on your phone:
From the homescreen, tap and hold the notification bar at the top and slide your finger down
Swipe your finger to the left to reveal more options
Tap and hold Mobile data
Tap Network mode
If you want to use 4G, make sure LTE/WCDMA/GSM is enabled. If you just want to connect to our 3G network, make sure WCDMA/GSM is enabled.
Seems we made things right.
Thanks for the feedback.
