F451 Error - Unable to link T-Mobile home internet phone number

I just signed up for T-Mobile home internet and am trying to link my home internet phone number to my account and it keeps taking me to the ‘F451 : Uh-oh, it looks like we have our wires crossed. Please try again later.’ error page. Just got off a 1.5 hour support call with no resolution. They keep asking me to try signing up using a different email address which doesn’t work. The system responds saying I need to use the email address I provided when signing up for home internet service.

Would be great to somehow get this resolved in the next month so I can pay my first bill.

I’m seeing a lot of complaints about this, which does not give me a good feeling about switching to T-Mobile. For people that are only Home Internet customers, not matter what we do, we can’t create an account. One method of creating an account says it doesn’t recognize the email address, but then if you create a forum account and try to link the phone number you are give with the Home Internet account, it give the Service Unavailable error. This is really bad and they will end up losing customers because of it. It’s insane to me that so many people have reported this over the last year or so, including some people making many calls to customer service, and they still haven’t fixed the problem.

I'm dealing with this now and no one can help me

Having the same issue and tech support couldn’t help either. This website suggests it’s all about ad-blockers:
