A recent article by MyBroadband explored how the popularity of VoIP services like WhatsApp has impacted voice income for South African major mobile networks: Vodacom, MTN, Telkom and Cell C.
- Vodacom has experienced a “slight decrease in the consumption of traditional voice minutes”, but said the advantages of traditional GSM calls still make it a good option for consumers.
- MTN told MyBroadband that it has “experienced a decrease in traditional calls and an increase in VoIP usage to match”.
- Cell C admitted they had noticed a decrease in the amount of traditional call minutes being used, but said that it had stabilised.
- Telkom told MyBroadband that it had “not seen a decrease in the average minutes of use per user for both on and off-network calling”.
However, according to We are Social, “WhatsApp is the biggest messaging app … in South Africa. We have 38-million unique mobile users, which grew by two million between 2017 and 2018. ”
The high costs of data in South Africa prevent many users from using WhatsApp’s full capabilities.
