Google Voice will also be unworkable for your needs. More and more businesses prohibit customers from using anything except a cell phone number from a major carrier or MVNO reseller, perhaps assuming anything else is criminal activity. Customer service agents are never trained about this, so they'll say a number is "invalid" or "voip" (regardless of the actual service used) and cannot be used.

I still use GV and have only run into a few services that won't take my number. None are critical, I just don't use those services.

Occasionally, I have GV refused for 2FA - but mostly it's fine. For Voice and text, GV has been more reliable than T-Mobile or AT&T.

Caveat: T-Mobile blocks outgoing GV calls from my handset 100% of the time. I have to turn on a VPN to make a GV call.

Mostly the same for me. But man it is fun discovering that an anti-VOIP check was added to a service after I had already associated my GV number years earlier. And now every single text 2FA prompt is sent directly into the aether.

Luckily that's only happened twice in 4+ years and both times they had an email recovery flow.
