Powered by the Fon WiFi SDK

The Fon WiFi app utilizes all the features of our cutting-edge SDK:

  • Intelligent network selection
  • Automatic user authentication
  • Minimum power consumption

Security at the core

User credentials are always secured

WiFi connections are established based on HTTPS with encoded communication and Fon also establishes tunnels (IPSec) for data to safely cross the Internet.

Fon connectivity tools are always secured

The combination of WiFi signal (SSID) and captive portal is double checked, to prevent devices from connecting to rogue hotspots.

Fon community network is always secured

All routers in our network are Fon-certified and double isolation is in place, to separate public and private sub-networks, as well as the isolation of WiFi users who are connected to the same public signal. We also insist on second phase authentication using temporary credentials.

Let’s work together

Are you already a partner of Fon? Do you want to boost WiFi traffic on your network? Why not launch the Fon WiFi app in your region.

Using the most relevant way to deliver WiFi connectivity to end users, the Fon WiFi app will help you reach an even wider audience. With such a simple user experience, you can be sure that customers will come back again and again.

Our SDK in action

case studies

The approach

For a limited time, Airbnb guests received a promo code with each booking, which unlocked five days of free WiFi. When redeemed either through our dedicated app or webpage, this promo code gave travellers automatic and seamless WiFi access when out and about in their destination.

The results

Access to Fon’s quality WiFi network enabled Airbnb guests to make the most of their travel experience, without needing to search for free WiFi or incur expensive data roaming charges.

The approach

Eurona is the exclusive provider of WiFi for travellers in airports across Spain. Through a captive portal, customers can choose from a range of free or paid WiFi access options.

The results

By integrating with Fon’s extensive, global footprint, Eurona have expanded their nationwide WiFi coverage, meaning travellers can stay connected not only at the airport, but also in their destination city.

The approach

Thanks to a long-standing partnership with the leading French telco, SFR, we’ve jointly grown and now manage a network made up of millions of WiFi hotspots across France. For years, both existing SFR customers and new visitors have been able to purchase WiFi access passes through an online captive portal.

The results

In 2017, we launched the Fon WiFi app across France, giving customers an even simpler way to buy WiFi access passes, with an enhanced mobile user-experience.
