>But blocked legit users who ported their real phone numbers to VoIP, like I did. Google won't verify an account against my home phone line anymore.

weird. i use a voip phone service, but twilio identifies it as a landline. maybe you're not using a fixed location voip service?

I use Google Fi as my mobile carrier. It is blocked from virtually everything even though it is a legitimate Sprint+T-Mobile sim.

Really? It should identify as a T-Mobile number. Have you tried contacting Fi support?

Yeah. I was one of the earlier users, the number identifies as GV-Grandcentral, formerly Bandwidth

It's basically rejected from every messenger, I can't use it with paypal or banking, etc.

Same problem but with normal google voice numbers. Really frustrating.

I want to use virtual numbers to avoid the spammers. There have been plenty of companies that had pseudo dodgy signup (win a chance for a dream trip to somewhere) where you had to give up your phone number (supposedly so they could call you). Lots of time I get spam calls that claim I gave permission for them to call me. So a temporary forwarding number hides me. I use my google voice number for this and it does a good job of noticing lots of spammers (but not all).

The google fi number isn’t your T-Mobile phone number. There is actually a way to find the actual t-mobile phone number that Fi forwards to, perhaps you can get that and use it instead.

Google Fi is Google Voice routed through T-mobiles network

I'm using voip.ms with an E911 registered location. We've used the number for years with traditional carriers. The service has been great for a good price otherwise.

We offer users an easy way to contact us to request manual whitelisting. It's painless, fast, and we find that not much abuse gets through when they have to write in messages to get in.

Who are "we"?

You have commented twice saying "We." And it is not clear who the "we" is. Do you work for mailinator, Twilio, Google?

Sorry, I was commenting from the perspective of a company that uses phone verification for account signups to help with fraud. I am not affiliated with any of the listed company.
