I have a google phone # how can I find out what my original number
Your phone number should be listed in the phone settings menu under “about phone.” Go to “Status” and then go to “SIM status” and the phone number should be there.
Just to add to @marshallh 's method…
You can open the RW app and select the Gear Icon(cog, top right) and select “about” as well. (at least I can on the Moto Pure).
