Pioneers of residential WiFi sharing


We revolutionised carrier WiFi with our technology, creating a globally connected WiFi network. Fon started as an innovative idea that has evolved into an established international company.

Our story


In 2006, serial entrepreneur Martin Varsavsky founded Fon with the mission of blanketing the world with WiFi. Pioneers of residential WiFi sharing, we revolutionised carrier WiFi with our technology.


Through strategic partnerships with leading telecommunication companies on five continents including British Telecom, the Deutsche Telekom Group, SFR, Proximus, KPN, Cosmote, MWEB, SoftBank, Telstra, and Vodafone among others, we have created a globally connected WiFi network.


With more than a decade of experience providing carrier WiFi services around the world, our technology is used to manage more than 20 million hotspots across five continents, and we wanted to use our expertise and unique technology to help our clients build and manage their very own WiFi networks. While still committed to providing WiFi access worldwide, we have continued to innovate through two leading business areas.


Fon Solutions offers best-in-class WiFi products and services. Designed with communications service providers (CSPs) in mind, our cutting-edge platform Fon WiFi Service Management Platform (WSMP) allows these companies to deploy, configure and operate carrier-class WiFi services on hotspot networks.


Fon Network aggregates residential and premium carrier WiFi footprints creating one coherent global WiFi network. We facilitate WiFi interconnection between carriers, provide access deals to interested parties, like enterprises and device manufacturers, and enable seamless user roaming.


As the world’s leading carrier WiFi provider, we believe in a future where people connect to millions of WiFi hotspots – seamlessly, securely, and everywhere.

Fon hit the 20 million Fon hotspots mark and built a robust carrier-grade solution for CSPs so they can manage WiFi services

Our partners share our vision


At Fon, we bring together a unique group of top tier investors, who pursue very different businesses, but all share our vision of making WiFi more accessible.
