CAPE TOWN - New information has revealed that an average WhatsApp call uses anything from 0.15 MB to 0.47 Mb per minute, according to a Quora forum finding.
This means that making a three-minute call over WhatsApp instead of regular cellphone call can save you as much as R3, according to a report by Business Insider.
However, the price difference vary depending on which service provider you use. Additionally, the quality of WhatsApp calls are heavily dependent on network strength and it isn't always the best option to use.
According to Business Insider, cellular calls cost R1.23 per minute at Vodacom, 99c at MTN, 66c at CellC and 70c at Telkom.
Apart from Vodacom, these rates are the same for pay-as-you-go and contract clients. You’d save at least R3.48 calling on WhatsApp at Vodacom, rather than cellular, reported Business Insider.
