onoff is the first telecom operator in the cloud!
A revolutionary hybrid operator (combining traditional telecom technologies with advanced OTT services), onoff have built the leading mobile app for enabling multiple phone numbers on a single device. onoff allows users to manage multiple numbers from any country and from one physical SIM card and device and to switch them “on” or “off” with one click: personal, professional, international, temporary and more. They are the only provider to offer world portability, offering users the ability to keep several, international numbers while only paying for one package.
onoff was founded by Taïg Khris, former multi-time rollerblade world champion.
