Hi all! I have a galaxy s4 (m919), and I'm wondering if I can swap the motherboard on the phone to phones on different carriers. It's not on a plan right now, and I can get it unlocked if I need it to.
 
Solution
If the phone is unlocked it should work for any carrier that you have the right antenna/modem for. That one might be both, not sure, I'm not good with phones, too tiny for big hands. The carriers go by ICC/IED/SIM numbers, part of those to all of those are locked to the motherboard, so you would have to power on as it would no longer match the number on the sticker of the case.
