I had windows 10 in my surface. I download from the microsoft webpage the original windows 8 image and then I installed the original windows 8 and then I enter to the attallaccess application with my local simcard provider in Peru and appears the option to enter the unlock code from att. After that I can use my local simcard provider and I proceed to upload to the windows 10 without problems.

The same thing has happened to me with my surface. I’m in the US and I received a unlock code from ATT I believe it’s a 16 digit number but I don’t know where I can type it in. I have put different SIM cards in my device and they show the carrier but say no service if I putt an ATT Sim it works just fine and I tried the app but I only have the 2 activate options. Can you please assist me as well?

Thank you for posting the solution.  It should have been posted on the public forum by ATT Support.  Apparently it’s top secret 🙄.   

Hopefully others will find your post if they have the same question.

Thank you for the reply.
So the only way to get it unlocked is to downgrade to windows 8, do you
have to buy a license for windows 8? Then upgrade back to windows 10, will
all my settings and apps remain the same through this whole process?

You need a format the windows 10 that mean you will lost the configuration and data stored in your surface. You need a do a backup of your data before downgrade to windows 8. If you use the original operative system for the surface you will not enter any windows product key the new installation detect the original product key but you need the product key to return to windows 10. Before format you surface you can copy the product key of the windows 10. You can find the producedure browsing in the internet.

I followed MS instructions and could not get my S3 AT&T to recover from the recovery USB: volume down + power button... Select US, Use a device, USB... then it would get back to the same selection process
 
I have two S3 AT&T tablets and got the prompt for unlock code on one within the generic Windows 8.1 pro. 
It was a 5.xx.xx version of AT&T Communication manager/All Access.  I have since wiped the tablet and installed Windows 10 on it.  I didn't document how I got it installed as I had tried install/uninstall of quite a few versions and repeatedly.
 
Since then I have failed to load the same version of the utility on my other S3 (it appears only downloadable/installable for Windows 10) and failed to get any other version to produce the prompt for unlock code.  I hope the 8.1 recovery image contains the version that will prompt for unlock code.

I just managed to restore from the Microsoft Windows 8.1 image for my S3, and see AT&T AllAccess version 4.0.2.581 included.  Yet the utility still does not prompt for unlock code (with a T-Mobile sim inserted that the OS can detect).  I am trying some other things now.

I am trying to do the same thing with a Surface 3 I am working with. Have you made any progress over the past few days? Do you know what version of the AT&T AllAccess/Communications Manager is required for the unlock code prompt to appear? And if you have gotten it working, is there any chance you can link the specific Windows image used?
