US Phone from Abroad that accepts automated texts?

Question. I am American but live abroad. I still have a US bank account and credit card as I have some US bills and want to maintain my credit score. They require a US phone number. I used a Skype phone number and that worked until recently.

Now my credit card has switched to a two step authentication method using text message. The problem is Skype does not accept automated text messages. Google voice had similar problems.

I visited the US recently and bought a prepaid Tracphone to have access to text. Unfortunately, (didn't realize this when I bought it.) Tracphone ceases to accept text messages or phone calls when you are outside the USA. There is an international plan that can be used temporarily but isn't a long term solution.

Does anyone know any phone service that can provide a US phone number that WILL 100% accept automated text and phone calls from banks/credit cards and is not tracphone, Skype or Google voice?
