Maybe we can build some sort of a "reverse proxy" solution where you can get a number from Twilio etc and just forward to an actual phone number from your carrier. Bonsu, you can add some "firewall" rules and boom. If you lose your phone from your carrier, your twilio number is the same. Just change the rule in Twilio ? Isn't there a service like this already ? If not, there is your billion dollar startup idea.
