I registered a mobile phone number with my friend's identity and account and used my own email to sign up for T-mobile and tie it to the number. Some time ago I changed the attribution of the number to me. When I logged into T-mobile again, it sent the verification code to my number as usual, but when I managed to log in, I didn't see any subscriptions. When I try to re-link it tells me that the number is already link to another account, but in fact I've only ever been link to the email account I'm currently using.
