Adding more prominence for the mobile messaging application Whatsapp, Smartphone users in India started getting their free voice calling feature in their app.
The addition of voice calling service is also emerging with other messaging applications, where recently Homegrown chat application Hike introduced the feature after making it’s first acquisition – a free calling application – Zip Phone.
Considering the largest user base of Whatsapp, the feature seems to further boost it, as the free calling service can be attained only by referral basis. Which means that a person who has the free voice calling feature can send an invite to his friends, which would enable them to install the feature.
WhatsApp has rolled out its new free voice-calling feature to a few users India which appears to be available on invite-only basis, as of now. The invite-only basis basically means that users will get a call through WhatsApp from someone who already has the feature updated. The feature is also restricted to Android only and you will need the updated 2.11.508 version to access the app.
