Can I replace the logic board of Galaxy s4 att (SGH-i337) with a logic board of a different carrier?

[Daniel Li2]

So my sister has this galaxy s4 , but it's broken in that there would be no audio when calls are made or received. This was a problem well ... because its a phone! My dad took the s4 and went to different shops to repair it. But he found no luck. The warranty expired on the phone too. So 2 weeks ago, I decided to buy a used S4 online, so i can replace the logic board. It worked!(the used s4 was pretty cheap too) The audio during calls problem was fixed. However, a week later, the s4 had another problem. I kept getting a message saying "SIM card removed, network is unavailable" or something like that. I would have to restart the phone to fix this. BUT this message would pop up 2 or 3 times a day. It gets really annoying. I tried looking up the solution online, but most of the responses were to send it back to Samsung or ATT with warranty. I don't have warranty on this anymore. So should I buy another logicboard? and if so, can i buy an s4 from a different carrier? lets say, from sprint, would that be compatible?

Welcome to the forums. To be on the safe side, I would stick to buying parts for the exact model you have.
