So I unlocked my att Samsung galaxy note 3 and I just connected it to tmobile today and it doesent show 4g lte it just shows h+ anyone know what I can do to get 4g lte?
I would check my APN settings to make sure they are correct for TMO.
I would also check my location and see if they have 1900mhz re-farmed for LTE.
Most ATT phones dont have the 1700mhz / 2100mhz that TMO started out with and has most of their LTE network on.
Id also check to make sure your area has LTE. Not all TMO areas have it yet.
