There is AT&T official unlock service that makes it possible to unlock AT&T iPhone 5 with iOS 7.1 at an affordable price. It is worth mentioning that the service is also available to iOS 7.1 smartphone, iOS 7.0.6 and any other firmware that supports Apple handsets. Besides, users are able to become SIM-free even if they are using iPhone 5S, 5c, 4S or 4 as some methods we’ll talk about are good for these models and operating systems as well.
You know that if you are on contract AT&T will not accept your unlock request. You can use AT&T out of contract checker to find out the status of your iPhone.
There are several unlocking methods you can choose for AT&T official unlock for iPhone 5. The first one is related with jailbreaking. iOS 7.1 can be jailbroken with Evasi0n7 program. This is the only way to jailbreak and it is completely free to use though you can do this at your own risk only. SAM unlock is a free unlock for AT&T contract and out of contract iPhone which works for users who saved activation tickets for SAM a couple of years ago. Without those tickets you will fail to unlock your handset.
Another method that also relies on jailbreak is called R-SIM 8 / 9 SIM unlock. This tool currently supports iPhone 4S, but its creators promise that iPhone 5 unlock via GEVEY is coming soon.
Unlock AT&T iPhone 5S
The best working AT&T official unlock is IMEI unlock or factory unlock. It supports all current Apple models, version of iOS and basebands. It is affordable and fast even though the new strict policy introduced last year by AT&T slowed down this process. Good companies can unlock smartphones within 24 hours though sometimes it takes up to 24 days to deliver the solution.
In order to use such a service, you need to first make sure your smartphone is locked to AT&T and activated with its network. Then you need to see that your IMEI code is not barred. Run iPhone carrier checker to see this information. If the code is clean and not blacklisted, you are eligible for painless unlock.
