Company History

Our foundations

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.

Comfone has been a major contributor to the evolution and innovation of roaming services since 1991. Below is a chronological overview of the major company milestones.

Roaming Relations Management

In 2021, Comfone officially launched their Roaming Relations Management service. This service, powered by the Key2roam Hub, allows MNOs and MVNOs to expand their coverage and outsource their roaming management without compromising resources. Operators can utilise Comfone’s wealth of experience and good relationships maintained over 20 years in the industry to establish and manage direct roaming connections, providing access to an unparalleled number of operators around the world.

Phoenix, the service fulfilling the BCE standard

Comfone continues to contribute to the evolution of the roaming industry by actively participating in the design of the BCE (Billing & Charging Evolution) standards at GSMA level. These activities, combined with agile development techniques, allowed Comfone to support live BCE trials in 2020 and develop a bright new BCE based service: Phoenix. Phoenix is fully integrated in the Key2roam Platform, in the Clearing Services layer. It fully supports BCE standard processes as defined by GSMA, qualifying Comfone as a BCE Provider.

Company shares taken over by the next generation

Daniel Heutschi, Christoph and Marc Stadelmann took over the TOGEWA shares from Géraldine Philippe, Walter Heutschi and Toni Stadelmann. This historic move ensures the longevity of Comfone as a privately owned, family-run business, allowing the company to continue along the same path as it always has. Our history of entrepreneurial spirit, courage and wisdom has been passed down to the next generation, and Comfone continues to run with peace of mind for a secure future.
