Fon is the global WiFi network

We’ve built the world’s largest community WiFi network of over 23 million hotspots.

Our story

In 2006, serial entrepreneur Martin Varsavsky founded Fon with the mission of blanketing the world with WiFi.

Driven by a community WiFi approach, and through strategic partnerships with leading telecommunication companies and WiFi providers including British Telecom, Deutsche Telekom Group, SFR, SoftBank, Telstra, KPN, Proximus, Vodafone, Virgin Media, and The Cloud, we have created a globally connected WiFi network.

Our footprint is now made up of over 23 million hotspots worldwide and it’s growing every day. We have achieved this growth by aggregating both residential and prime public WiFi footprints, as well as facilitating interconnection between WiFi services.

We are experts in keeping people seamlessly connected and our goal is to connect people and businesses to WiFi, wherever and whenever they need it.

While we continue to focus on growing our global network, we wanted to take our experience and unique technology further and enable our clients to build and manage their very own WiFi networks and offer value-added, WiFi-based services. For this reason, we launched Fontech, our technology arm that makes managing WiFi smart and simple.
