Your number.
Every country.
One SIM that follows you over data instead of a tower. No roaming fee, no second number to give out, no "sorry, this is my temporary Japan number."
Watch it switch countries — same number
This is a working simulation you can play with. Pick a country, connect, and send a message. Nothing here touches a real network yet.
How it actually works
Three real steps behind the concept — this is the part that needs genuine telecom infrastructure, not just an app.
Your number gets a data identity
Instead of living on a physical SIM tied to one carrier, your number is registered with a provider (like Twilio) that can route calls and texts over the internet.
The app keeps you reachable
Wherever you have Wi-Fi or mobile data, the app maintains a connection so calls and texts find you — no local SIM swap required.
Local carriers still matter
Full parity with a real cell signal (emergency calls, no-data areas) needs actual carrier agreements per country — the genuinely hard, non-app part.
Coverage, if this became real
Realistic v1 scope: strong Wi-Fi/data coverage markets first, before chasing full global carrier parity.
