Amid the price war, Indian telecom companies are hitting not only each other but also WhatsApp. This is because WhatsApp has significantly replaced SMS and voice calls. Many app companies also failed to bump it. However, now a new name is going to be added to app companies like Facebook Messenger, Geochat, Hike and WeChat. Government company BSNL is now set to spread its foothold in this segment. The company has started testing its new Voice Over Wi-Fi service. Let us know the full details Vodafone changes its plan to compete Airtel and Jio Under this service, users will be able to make outgoing calls even in poor cellular connectivity. Also, you'll be able to connect to any public hotspot or any standard Wi-Fi network. In fact, this service will also allow users to be out-of-going on landline and mobile numbers. BSNL made these special changes to its Bharat Fiber broadband plan When it comes to the difference between voice over Wi-Fi and WhatsApp, VoWiFi doesn't need to install any third-party apps. This is the first difference. On the other hand, in WhatsApp, if you want to call or message someone, the other person must also be connected to the Internet. But voice over Wi-Fi doesn't have any such trouble. BSNL VoWiFi users will be able to make calls from their phone's dialer app. BSNL wants to deliver this service to cities or places in India where network problems persist, apart from Tier-2 and Tier-3. Users will also not be required to pay a separate charge for using BSNL's service. To use this technology, the user's mobile must be VoLTE and VoWiFi enabled.
