Hey guys trying to figure this out here hopefully somebody can chime in. I recently sent and received a tmobile iPhone 6 plus for for repair to apple. Today i received back a replacement device. When i check my imei through swappa, checkesnfree, and even the verizon website, all come back as the device being verizon. Does apple perhaps send back a contract free phone when tmobile phones are serviced? i have however tried to insert a non tmobile sim in the phone, and i get a prompt indicated that they sim card isn't valid for this device. Any help would be greatly appreciated. i am planning on reselling the device, or possible keep it for my own use on verizon once but trying to figure this out first.
