So I was wondering how the insurance filing works with AT&T. My question is that if I do buy insurance from AT&T and report my phone broke, ( Dropped from 2 stories etc...) When I receive my replacement will AT&T completely block the other phone? So will they block the IMEI from there database, or can I just go get Straight Talk or something and pop that sim in or maybe T-Mobile since they offer Nano Sim. Thanks for your responses I really appreciate it !
