Great. How so we resolve this? Your phone-based support told me they couldn't resolve it. My phone number is (Edited as per community guidelines).

@tovbrog Please edit your post to remove your phone number.  No one is going to call you except the scammers and spammers you’ve given your number to.

So if I understanding your original post, you have an email security problem because the phone number used for two-factor authentication no longer exists. This is not a wireless problem

It's really important but before you lose a phone number, cancel it, give it up, default on whatever account is connected to etc that you make sure that your email security has been switched to a different phone number.

I have moved this to the email security and login section of the forum which is where it apparently belongs

Not a wireless problem. This is an email login problem

This is an account login problem. I don't use an AT&T email account. 

Your AT&T two-factor authentication would be going to another phone on your account. You're saying it's not?   Is the phone number canceled or transferred to a different AT&T account?

It's going to a phone that no longer exists. It might be from when we had directv 20 years ago.
