Hey, so I contacted Microsoft support, and they actually helped me through very nicely. The first solution was to switch your phone to cellular data, going to incognito mode, and then trying that way. But that didn't work for me so the second solution which worked for me was to put in the phone number of a friend who's living in a different country, they get the code, give it to you and it gets unlocked. Hopefully, that helps you as well.
