Onoff Group

At Onoff Group, our goal is to reinvent the telecom user experience. We focus on revolutionizing the business telephony of all types and sizes of companies with our Onoff Business solution. We are a team of 120 passionate people from all around the world, with offices in Paris and Tallinn. Six years ago, we released a mobile application that finally made it possible to use multiple phone numbers on the same device, with the same SIM card. Since then, we've added more than 30 number nationalities, along with calls to nearly 150 destinations worldwide. We believe that calling someone should be as flexible as using your email - accessible from anywhere, anytime. And obviously not as expensive as it currently is made up to be.
