WhatsApp voice calling feature is not free actually, Like Skype, Viber, Facebook and many more WhatsApp is giving free calling feature to its users which has high call drop rates than network calls and even costlier too…
Users need to update to WhatsApp version 2.12.5 (or above) to get the calling feature.
WhatsApp calling has finally arrived. WhatsApp users will need to update to version 2.12.5 (or above) from Google Play. If the update is not available directly from Google Play, users can get the latest version from here. The calling feature will automatically get activated after updating the app. Both caller and receiver has to update to the latest version to use the calling feature.
If I’m using WhatsApp via Wi-Fi through an existing internet connection – the costs may come down. But I doubt people will always look for a free Wi-Fi signal to make calls.
WhatsApp calling allow users to call other WhatsApp users for free. However, a minute of WhatsApp call costs around 0.15 MB to 0.20 MB of 3G data This means a 5-minute call costs around 1MB of 3G data. The call quality on 3G networks is decent but on 2G, there is a considerable amount of lag. Also, on 2G, a minute of WhatsApp call costs around 0.35MB which is surprisingly higher than 3G.
Of course it’s bound to be cheaper when you are making international calls; but for the local calls which, in India, cost 1p/second I think the price is tough to beat! You’re bound to consume more data transferring audio signals over the data connection.
Without mobile internet plans, the standard data rates for most operators are 4p /10 KB (3G) and 10p / 10 KB (2G). This roughly translates to Re 1 per minute of WhatsApp call on 3G and Rs 2.50 per minute on 2G network.
During a WhatsApp call, if the user gets a regular call on his smart phone, then the WhatsApp call runs in background for a few seconds and gets disconnected on its own.
