In August 2006, Wifi UMA based service was launched by service provider telecom company "Teliasonera" in Denmark.

This service was named "Free Home". And it became known as the first Wi-Fi Calling service. Bluetooth-based service was discontinued from here. After this, in September 2006, Orange launched it as a unique service, also known as "Signal Boost".

When Wifi Calling started in 2007, big brands like Nokiya, Samsung, Motorola introduced their phones. They had UAE based 802.11 wireless network support. After this, this service was gradually introduced in many countries of the world. By 2015, big names like "AT&T" and "Verizon" were added to it.

As for India, Airtel started it from Delhi NCR on 10 December 2019. A few days later, Jio also launched its Wifi Calling. However, when Airtel started its wifi calling service, this service worked only on Airtel's WiFi.
