Thank you for taking the time to e-mail AT&T to request the device
un-lock code for your iPhone.
The IMEI you provided is not eligible to be unlocked because of security
restrictions. Non AT&T customers are not eligible to have their iPhone
unlocked through AT&T. AT&T will unlock an iPhone under the following
circumstances:
? The person requesting the unlock is a current AT&T customer or a
former AT&T customer who can provide the phone number or account number
for the account

obligations, including any term commitment, associated with the device
to be unlocked have been fully satisfied.

Also, current customer accounts must be in good standing with no
