Our calls lasted for six minutes and we ran our tests on LTE. In our tests it only makes sense to use WhatsApp calling while on Wi-Fi.

We're not attaching a specific dollar figure to this test because every mobile plan is different, but the averages we got should at least give you an idea of whether or not relying on WhatsApp for voice calls is actually economically better than using traditional call minutes. We provide both figures below and averaged them out (along with averages of the various calls we recorded). We made a series of WhatsApp calls and measured the data consumption with two tools: the figures given by the Android system itself and an app that measures data rates called Data Monitor. The first thing you're going to want to know is how we came up with our figures.
