I have an AT&T Note 8 that seems to be blacklisted with AT&T only. When I do an IMEI look up on Swappa, Ting, and other sites it comes up as clean and not blacklisted at all. My question is, which unlock do I pay for? If I do the blacklisted one will that unlock the phone for domestic use as well? When I check the IMEI with Verizon (My current carrier) it comes up just fine and ready to activate. Will the SIM unlock work for Verizon?
