Finally got back my T-mobile account (yes, it was a sim swap, meaning that someone socially-engineered T-mobile itself to take over my phone number).

have seen a lot of this sim swaps but no post mortems on best practices to quickly recover your accounts - would really love to see something like this. i have no idea who you'd even reach out to in this situation

stake responsibly // be a kind human // slomad

Ko Lanta Yai, Ko Lanta District, Krabi, Thailand

As a victim of being swim swapped in the past. I had to go to the store and recover my account in person. 
I couldn't call because, I didn't have a lan line and it was late at night.
