Orange has been the company's main brand for mobile, landline, internet and IPTV services since 2006.

Orange is the sole brand used in the marketing of the company's mobile offers; the Itineris, Ola and Mobicarte brands have been combined since 2001, and Mobicarte became a special prepaid calling offer.
