Yeah, that's a good workaround. Google Voice can work too.

Unfortunately, more and more services are declining to send to VoIP numbers because of seCurItY, so it's a game of cat and mouse.

Fortunately SMS is so expensive in parts of Europe and it's not allowable anymore to use SMS by itself for online payment authentication, and both issues combined have slowly been pushing companies to explore alternatives.

There unfortunately seems to be no such pressure in the US. Passkeys could solve the issue, but probably increase support request volumes enough for most companies to not bother unless forced.
