MyBroadband Insights has released its 2023 Mobile Voice Network Quality Report, which shows that MTN has the best mobile voice service in South Africa.

The report is based on South Africa’s biggest-ever mobile network quality test, conducted between 20 March and 24 April.

Over the testing period, MyBroadband Insights travelled over 10,000 kilometres, made 93,912 calls, and recorded over 41,000 call minutes.

MyBroadband Insights partnered with Analytico and Keysight distributor Coral-i for the extensive, country-wide network testing project.

This project used Keysight’s world-leading network testing platform, Nemo, to test a range of voice network quality variables.

Network performance was also measured according to the latest End-user and Subscriber Charter from the industry regulator ICASA.

The regulations require mobile operators to achieve an Average Call Setup Success Ratio (CSSR) of 98% and an Average Dropped Call Ratio (DCR) of below 3%.

It further requires an Average Call Setup Time (CST) of below 9 seconds and an Average Speech Quality Mean Opinion Score (MOS) of higher than 3.

MyBroadband Insights used the globally recognised European Telecommunications Standards Institute (ETSI) specification to rank the mobile operators’ voice network quality.
