Yea, my dumbass used Google voice as my main 2fa number and recently lost access to it. Can't get it back and I'm locked out of everything. Don't be like me. Google really can't be trusted for personal or business use. If I could talk to a human and pay $100 for it I would.
I used to live in the US and use voice as my primary number for everything. I don't think there is a better option.
