[deleted] I know your question wasn't directed to me but I'll answer it.
I initially created my account on my old Galaxy 10.When I got my P8P, I transferred it across to the Pixel. It took a bit of work because it wouldn't work for a while. Eventually, as I fiddled about, I managed to get it to work.
I don't have a phone number with it (only emails) because I don't live in the USA. The payment method for purchasing a Mysudo number is through Google pay - which I'm not going to go through because it identifies me. I'm looking at Silent Link, flynumber and voip.ms as alternatives for use in my authoritarian country.
