Airtel has launched Wi-Fi calling after testing it for months, but for now it will work only on Airtel Xstream Fiber and on select smartphones.
The Wi-Fi calling is being rolled out for prepaid and postpaid subscribers across the country, according to Airtel here on Tuesday. "It is currently available in Delhi NCR and will be gradually rolled out across India," it said.
The Wi-Fi calling will let Airtel users make use of the Wi-Fi network in their homes to make calls using VoIP, instead of relying on cellular connectivity. There will be no extra charge for calls made over Airtel Wi-Fi calling and the application consumes minimal data.
Reliance Jio is also working on a similar feature and is expected to launch it soon.
