So I work at a little repair shop and was looking at parts and the idea crossed my mind If you swapped the whole charging/SIM board (they are one piece) from the US variant to the Dual sim/ international would it work or even function properly? Feel free to let me know if you guys have any...

I recently adquired a Sony Xperia M4 Aqua, and all seems to be alright, it has had no repairs and never been dunked into water before, so a week ago I found that the phone screen had gone black, at simple view you could tell it was on. I pressed the power button a few times and it seemed to lock...

I want to get the Moto G and Use it with a $30 or $35 plan but it seems that I can. Do I have to dig around to find a plan that works with it?
