 Super helpful. What about taking your physical SIM and transferring to Signal ? P.s. I owe you a follow up email.

If we spoke via email, please use the protonmail, the other one had issues 
 I see. Was confusing the issue a bit. Trying to solve for moving existing numbers (tied to biz & personal) into an anonymous environment and off mainstream carriers
