Unlock ATT Lumia 640 XL to use with T-Mobile

T-Mobile offers Lumia 640 on its stores but not Lumia 640 XL which is a much bigger phone. AT&T sells it but it is locked to their network and one cannot use it unless they unlock it. It turns out that unlocking ATT Lumia 640 XL is not that difficult if the words of a reddit user are to be believed.

Unlock ATT Lumia 640 XL for T-Mobile

This reddit user went to a Windows Store to replace his old Lumia 521 with Lumia 640 XL. The phone was locked to AT&T but he bought it nevertheless. Since he had a strong hate for AT&T and wanted to use his T-Mobile SIM, he submitted his IMEI umber to AT&T along with some personal information.

The very next day, he got an email back with the unlock code which would allow him to use it to any cellular network.

Funny thing is he is not a current or former AT&T customer and he promises to never give a dime to them for the rest of his life.

Here is AT&T’s page for unlocking devices:
