I'm currently with At&t .. I've been trying to purchase a new phone from T-Mobile for about a good year now . And EACH time it won't let me because back in 2020 I had T-mobile . I payed that phone off and switched to At&t because T-mobile's app wouldn't let me trade in my phone and upgrade . I tried everything . The app was down for the longest . I no longer have access to that account, that number, and that phone . It lets me sign in with my old gmail on the app but an error pops up . So
I've been having problems with at&t so I wanted to switch back . I've tried for days , months , spoke with representatives and bosses and still nothing . I'm unable to purchase a new device with T-mobile because my SSN is still attached to an account that I no longer have . It's no longer in service . I just want to go back to T-mobile . What do I do 😑 and how do I get past them stopping me from purchasing a phone .
