Unlock code not provided by at&t

I have the same issue. ATT strangely said that Surface duo is not a supported device and manufacturer cant give an unlock pin.

I have tried many times now to unlock my surface duo in the att/unlockmydevice and everytime it keeps telling me the information is incorrect.

I have also called their customer support service and they couldn't get my unlock code.

How can I get my code from Microsoft??

Hi AlphaPonce Santamaria,

Please use the steps below to contact support and have the following information ready:

• IMEI of your Surface Duo
• Serial Number of your Surface Duo
• AT&T Case Number

Please go to: https://support.microsoft.com/contactus#!

1. Type in 'surface duo' in the box
2. Click 'Get Help'
3. On the bottom click "Contact Support" or "Sign n to contact support"
4. From the drop lists select the items that apply and then you will get a list of available options to get a support agent to contact you depending on your selected issue.

Only Surface Duo AT&T devices may need an unlock code. Surface Duo 2 and Surface Duo non-AT&T devices do not need unlock codes as they are unlocked devices.

AT&T can assist you further with your request. First, you need to submit a SIM unlock code request to AT&T by visiting http://att.com/deviceunlock  . You will need to provide the device IMEI (tap Settings, tap About and provide the IMEI number) and other requested information. AT&T will communicate order processing information via e-mail. If your phone is locked to AT&T but was not obtained through AT&T, either through another retailer or a replacement via a warranty exchange, then please allow additional time for AT&T to obtain the unlock code and respond to your request.

After submitting the request, you will receive an email from AT&T to validate your email address is correct. If you are unable to find that email, check your junk mail to see if it is there. You will need to respond to that email within 24 hours to validate your email address. If you do not respond within 24 hours, you will need to go back to http://att.com/deviceunlock  and submit a new request and then need to validate your email.

After validating your email address, you will receive another email from AT&T on the status of your request once it has been processed. It may take up to 5 business days to receive a response. If AT&T indicates that they are unable to provide you with an unlock code for your device, then contact Microsoft Support  for additional assistance.
