I have an old iPhone 3GS that is no more in everyday use, so I chose to give the unlock process a spin. This is what you have to do to unlock yours:

Give your IMEI number and be patient amid the unlock process. You'll additionally need to give an email location, where AT&T sends the unlock guidelines.
4. Sit tight for AT&T's email
For me, the email arrived several minutes subsequent to getting off the phone, yet different clients have reported any longer holds up.
5. At the point when the email touches base, move down and restore your iPhone in iTunes
Open iTunes on a PC that is joined with the Internet. Ensure your iPhone has a dynamic SIM card in it, then connect it to iTunes. Sync it with iTunes, then right-tap on the gadget under the "Gadgets" segment on the left half of the screen, and snap "Go down." Once that is done, right-tap on the gadget and selects "Restore from Backup."
On the off chance that all goes well, you ought to get the accompanying message in iTunes: "Unlock Complete. Congrats, your iPhone has unlock iphone 5 at&t. To set up and match up this iPhone, snap Continue." At this point, you ought to have the capacity to embed SIM cards from different bearers.
