OK first off my phone is the sprint HTC one pn0072 . currently running a custom rom (pacman ROM nightly) my question is , if I'm running this ROM can I use a T-Mobile sim card instead of sprint? If I go to mobile networks it gives me a whole bunch to choose from, would an att or T-Mobile sim work if I select the right network type . basically trying to find out if my phone is useable on another network . the options are there I just haven't tried. My sprint phone bills up and I wanna use the phone with family mobile or straight talk or something other than sprint. Bootloader unlocked and its s-off. hello please!
