How to unlock an Iphone

Your device is designed to work on the AT&T wireless network, and may require a device unlock to operate on another compatible wireless network.

AT&T can send you unlock instructions upon request, provided that we can reasonably obtain them from the manufacturer and that you meet the requirements below. You should receive a response within two business days.

How To Request A Device Unlock

1. Go to the Device Unlock Portal (page best viewed from a desktop or tablet).
2. Follow the prompt listed.  

To check status of your request

1. Go to our Status Portal.
2.  Enter your IMEI Number & Request Number.
3. Follow the prompts.

General Requirements for All Unlock Requests

to unlock the iphone, you need to backup and restore the phone using iTunes. That will complete the unlock. That is the only way to unlock an iPhone.

It is best to backup the phone and completely wipe the phone and then backup and restore as a new phone. You should get the unlock message.

Then you can restore the phone from any backup (either iTunes or Cloud).

It seems you purchased a locked phone from someone and the phone is locked to the AT&T system. Here is a rather long thread concerning unlocking an AT&T phone and a link to the unlock policy...

Your best bet would probably be to return the phone for refund and purchase a phone in your local area that is capable of using your local phone systems.

It may be that the phone is reported lost or stolen. If that is the case, the phone will not be unlocked.

Since the phone is not usable, file a claim with eBay.

Once unlocked, it stays unlocked. 

@yami2003 Unlock it as a non-customer.

You will have to submit unlock request through the online form. If the phone does not belong to you, then you will have to find out who the owner of the phone is, and ask the owner to request the unlock request with att. 

Hi @shahrukh 

You can still submit a request even if you never had an AT&T account. See the information above and use the link to the online unlock portal to get started.

Thanks,

im a business customer, spend around $6,000 every month, and no doubt that ATT covers my necessity while abroad, however when asked to provide unlock for iphones they really are a pain, that makes me move to others carriers such as tmobile, since they have no restrictions in unlocking the phone at no problem, Ive been a customer for many years and I find this "unable to unlock" a sort of pushiment towards our loyalty, I mean I even researched if these was under constituion and Ive found out recently: "

President Barack Obama signed a bipartisan bill into law Friday that aims to make it easier for consumers to change their cell phone service providers without paying for a new phone.

The bill, known as the Unlocking Consumer Choice and Wireless Competition Act, reverses a decision made by the Library of Congress two years ago that said it was illegal for consumers to "unlock" their cell phones for use on other networks without their service provider's permission." under DMCA S.517 Why Att keep their unfair policy?

I called ATT and they simply told me that the phone must be in the account for at least 60 days

you have to request the unlock through online form. Or you can try call customer service at 18003310500 to get one of the rep to help you.
