The site targets individuals, freelancers and professionals. It lists a base plan with one national number, 1,000 call minutes and 1,000 SMS/MMS, a Premium option with features such as multi-device calling and availability scheduling, international calls paid with credits, and Onoff Business for companies that want numbers for employees. The company presents itself as Onoff Telecom, a telecommunications operator recognised by ARCEP.

The company lists offices in Paris (France) and Tallinn (Estonia). The website footer shows a 2022 copyright date. Its open roles are in Paris, Tallinn and Romania, across engineering, marketing, customer care, legal, sales and people operations.
