Let us set you on the right track of unlocking your device!
In order to have the device unlocked, it requires 60 days of postpaid or 6 months of prepaid service with no past due balance on the account. Also, the device’s service commitments and installment plans must be completed, and all early termination fees are paid in full.
We have a similar issue. Our phone has been out of service for four years. We purchased a new phone to take its place, on the same AT&T account. The IMEI # is correct. Is there any reason this can't be unlocked? Thanks~
