TMobile locked my AT&T Phone
Hi, I newly purchased AT&T Postpaid Iphone week before. During the activation Instead of AT&T SIM Card by mistake i put TMobile SIM Card into it (Ultra Mobile SIM Card) So my AT&T Phone got locked...
You need to contact Tmobile support because this is basically a user to user forum with some tmobile moderation that don't have account access so no one here can really help. All we can do is point you in a direction that may help.
And then the customer blames the first carrier they put the sim in that their unlocked phone is now locked.
