Hey its been a minute since ive been in the samsung space but I have a SM G991U that has been unclocked and now is on tmobile, however it doesnt appear to get Ultra capacity despite having the bands. Can some one direct me to what I need to do?

Edit: Did a firmupdate from phone, then it asked if I wanted to swtich to tmobile and it did another flash now the boot logo is tmo. Maybe this will work.

Edit2: This did fix it!
