Are there solid VoIP providers that aren't detected by 2FA SMS services? I can't use my Google Voice for a decent chunk of sign-ups because it is detected (and rejected) too easily. I hate getting spam, so I try to keep my primary phone number only for friends and family.

Serious question, what services are you using that this isn't a deal breaker for you? And why isn't it?

Most services either don't have a legitimate interest in my phone number (so they can get bent) or they do have a legitimate interest in which case not accepting my phone number means they aren't doing their #$&^ job (so they can get bent).

It helps that the only services I'm willing to provide my phone number to are those that already inherently involve my PII. Banks, online shopping, etc. So if they won't accept whatever I give them I'll take my business to a competitor.

I've used my Google Voice number as my primary number for ~15 years at this point. (I use my "real" phone number so little that I have trouble remembering it.)

I've had almost no problems using my GV number for 2FA. Venmo is literally the only service I've ever used that won't accept it for 2FA… and now Venmo offers non-SMS based alternatives, which is good because SMS-based 2FA is the reason that the SIM-swap attack is worth doing.

Use sms verification services that spammers use. They're implemented by using banks of sim cards placed in some apartment somewhere, so it's as "real" as it can get.

Objectively, it gets even worse in regions where Google voice isn't available. The only options seem to be online SMS portals where a relatively small set of numbers are shared across many users.

If anyone knows of a good, secure VoIP provider outside of the US I'd be keen to hear about it.

2FA mule.
