I bought an unlocked iPhone XR on eBay that was previously used with AT&T. I’m trying to use it on Verizon but am having issues. For starters, the phone says 3G even youth Verizon operates on a 4G network. I took it to Verizon & they said the phone should work but think AT&T hasn’t unlocked it. I confirmed with AT&T that it is unlocked. The only way the phone works is with wi-fi or the mobile hotspot through Verizon. I can’t even receive phone calls as is. Anyone have thoughts on what I need to do in order to get the phone to work properly?
Never buy a used phone from ebay
