Fon is the global WiFi network 


We pioneered residential WiFi sharing over a decade ago, revolutionizing carrier WiFi, and now we manage and continue to grow a global network of over 21 million hotspots worldwide. What started as an innovative idea has evolved into an established international business, specialising in global WiFi connectivity.

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 21 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.
