WhatsApp calling allow users to call other 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.

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. For Local and STD calls in India, it calls make little sense, even on 3Gdata, when the experience is compared to regular voice calls with per second pulse in cents. For international calls, WhatsApp calling is a great feature only if you are on WiFi. With the present state of 3G and 2G mobile Internet in the country, you simply cannot make an international call while on-the-go. The new WhatsApp calling interface is similar to the regular call UI in Android smartphones. Call records are automatically saved. 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.

While you can expect the call to get connected on 3G, WhatsApp call simply gets paralysed on 2G networks. When connected to WiFi, there are no issues with thecall as such apart from the echo problem. Overall, while using WhatsApp calls on mobile internet, it’s very difficult to have a conversation for more than two minutes.
