Unlock Eligibility requirements:
Look! The important legal stuff.
AT&T reserves the right to deny any unlock request that it concludes would result in an abuse of this policy or is part of an effort to defraud AT&T or its customers. AT&T further reserves the right to alter this unlocking policy at its discretion without advance notice. If during any one month, more than 100 requests are made from a single source, and if more than 10% of those requests are duplicate IMEI numbers, AT&T will no longer process unlock requests from that source.
