My Motorola G4 broke. I have no idea what's wrong with it; I can't answer any calls (can't hear anything); can't play video; can't record video. It seems to have to do with anything that addresses the speaker/microphone.
I purchased an unlocked LG G5 off eBay. When it arrives, can I simply transfer the SIM from the Motorola into the LG and activate, or do I have to buy a new SIM?
