What is Onoff Telecom?

Onoff is a telecommunications operator based in Paris and Tallinn.

Our ambition is to lift the boundaries of the world of telecommunications to offer you the best possible communication experience.

Onoff allows you to have several phone numbers, of different nationalities, on your smartphone. All without the need for a second SIM card or another mobile.
But it's much more than that: it's a fully virtualized communication experience, all in one app!
