Founded in 1997, Comfone is a result of a joint merger formed between Swisscom and Vodafone. Founders Walter Heutschi, Géraldine Philippe and Toni Stadelmann each played key roles in the development and evolution of roaming to what we know it as today.

In the years following the company foundation, Comfone proceeded to develop and launch a portfolio of first class roaming services, including Data and Financial Clearing, Signalling and GRX / IPX services and the Key2roam Hub. By the year 2010 Comfone was able to offer operators everything necessary in order to establish seamless, high quality roaming for their subscribers.

With a focus on quality and simplicity, in 2012 Comfone launched the Key2roam Platform, a complete solution that allows members to design their own setup by selecting and contracting only the service elements required.
