BSNL to take on WhatsAppWhatsApp is giving nightmares to Indian telcos. The Facebook-owned messenger has successfully replaced SMSs and even voice calls to a large extent. Not many Indian apps have been successful in challenging WhatsApp. There already is JioChat, Hike, Viber, WeChat and even Facebook Messenger, and now BSNL has started testing a new Voice over Wi-Fi (VoWiFi) to take on the top OTT players in the Indian market.
Voice over Wi-Fi enables users to make outgoing calls even where there is poor cellular connectivity. The VoWi-Fi feature lets you connect to a public Wi-Fi hotspot or any standard Wi-Fi network and make outgoing calls to mobile numbers and landlines. The difference between VoWi-Fi and the calling services provided by other apps like WhatsApp and Telegram is that VoWi-Fi doesn't need any third party app to be installed. Secondly, in the case of WhatsApp, the recipient has to be connected to the internet to get calls. Last of all, VoWiFi lets you dial outgoing calls right from your phone's dialer app.
