About Onoff

At OnOff, our goal is to reinvent the user experience in the world of telecommunications. We are a team based in Paris and Tallinn, made up of 100 passionate people from around the globe. In 2014, we launched the first version of a mobile app that finally allowed multiple phone numbers on a single device with the same SIM card. Since then, we’ve added numbers from more than 30 countries, as well as calling capabilities to nearly 150 destinations. We’re also very proud of our “Onoff Business” solution, which streamlines fleet management by assigning professional lines directly to your employees’ smartphones.
