Virtual Phone Number by Proton
It would be nice to have a app from Proton which gives a virtual phone number. (Like Google Voice)

https://youmai.com/ is in just this business. They operate primarily in the US. I could see this getting complicated to do on a global basis. Their use case is business numbers for small tradesmen, etc. to take business calls on a mobile without disclosing device phone number.
Many VoIP terrestrial carriers offer additional numbers. For example, OOMA Premier service includes a second in/out number. Can be set up to forward to mobile.
Noted by someone else who signed up for lots of Google stuff and now is fleeing them. I agree, great idea... I found another service to take over my GV number, and it's okay, but having it part of a package would be nice.
That's really great. This will improve users privacy
