Proceed to the AT&T web page

Look for the unlock request page since it will help you unlock the device. You will notice a section that reads accept terms. You need to click on it so that it can take you to the next page. Indicate that you are not a customer, then fill out the information that is needed. Some of the details include the IMEI number. This is often found on the box of your Lumia device. If you cannot find it, remove the battery of the device and look for it there. The sections labeled make and model should both read auto select. Submitting some character confirms that you are human and not a bot.

Provide your details

Once you have entered the characters as required, you should click on the button labeled Next. You then need to fill in some personal details. These include your first and last name. It is also important to fill in your email since this is the platform that AT&T will use to send you the unlock code.

Wait for the confirmation email

Check your email to see if you get a confirmation email related to the unlock request. On the email, you will see a link that you should click on to confirm the request.
