Several times world champion of rollerblading on ramps and, more broadly, high level athlete, Taïg Khris is the guest of Frenchweb to present his start-up OnOff Telecom. The concept: to host the phone numbers in the cloud, to make them independent of a SIM card. Thus, a telephone equipped with a single SIM card can receive calls from several numbers, just as it becomes possible to quickly change the telephone to receive calls from the same number. A simple download of the application is enough. More details with Taïg Khris.
