This is an alternative means by which you can AT&T unlock iPhone. It is a tad more cumbersome and may take a little more time, but is another legitimate means you could opt for should you wish to do so. This is done by directly getting in contact with your Carrier. If you already know that your carrier is AT&T, you can contact them directly and get your Apple iPhone 12 Pro Max unlocked as follows:

Step 1: Go to their Site and Contact them

1. Go to https://www.att.com/deviceunlock/?#/ first. This is the official location whereby you can contact them.

2. The page will list out certain eligibility requirements. You have to read and agree to them before clicking ‘Continue.’

However, AT&T has the right to dismiss anyone’s request based on several requirements and criteria, so your application may yet be either rejected or you may have to go through further steps. It is a good idea to go through their requirements before you fill their form.

1. The obvious requirement is that your Apple iPhone 12 Pro Max must be locked to AT&T, else you should go to the relevant carrier page.

2. You iPhone couldn’t have been reported as either lost or stolen.

3. No record of it having been linked to any criminal or fraudulent activities.

Both the options mentioned above offer a legitimate means by which you can AT&T unlock your Apple iPhone 12 Pro Max, whether done without a SIM card or by contacting the AT&T carrier.

However, going by personal experience the DoctorSIM alternative offers a much smoother, efficient and quicker alternative to contacting the AT&T carriers. It is also more secure because if you are going via the carrier without a SIM card then you’ll need to back up your Apple iPhone 12 Pro Max, then delete and restore it as well (for security measures). This isn’t just a time consuming process, but it can also prove to be risky. Furthermore, AT&T has a lot of checks and requisites in place which can keep your Apple iPhone 12 Pro Max from being unlocked, and even if you do pass the requisites it’s still a time-consuming process which may still be rejected as AT&T has final say. As such, going via DoctorSIM gives you complete agency and conveniently AT&T unlocks iPhone without any data loss, through a simple 3 step process.
