ATT has the worst policy on locked phones too. Say you buy a iPhone from Apple that works with ATT. Even if you pay in full it’s still locked. You have to contact ATT to get it unlocked. Verizon just has your phone locked for 30 or 60 days then they just unlock it. Seems like ATT is hoping you just don’t go through the hassle of unlocking it. I mean personally now I just get my phone through Apple and not carrier locked.
