may be this is a tactic to prevent user to transfer mile?? I'm new to VentureX. Amex never has issue. Has anyone successful transfer mile with Capital One?
Was the number being used previously acquired/transferred from a service like Google Voice or other VOIP-like provider? Many SMS MFA services don't like VOIP like numbers, it's possible that even though it's no longer VOIP (assuming you actually ported it to T-Mobile and are not attempting a forwarding solution) then whatever systems/databases they use to prevent these numbers might be out of date.

I have T-Mobile and haven't had any issues getting past the SMS MFA for Miles Transfer, so it must be something more than just all T-Mobile US.
