Vodacom’s high network reliability confirmed

Vodacom was announced as the joint winner of the 2024 MyBroadband Best Voice Network in South Africa award, confirming its status as the most reliable network in the country.

MyBroadband Insights conducted mobile network voice quality tests across South Africa between 15 May 2024 and 4 July 2024.

MyBroadband’s research engineer travelled 10,000 kilometres throughout South Africa and performed tests in all major cities, secondary cities, large towns, and major roads.

The testing included 38,000 calls and over 633 hours of recorded call data, making it the largest-ever voice network quality testing project in South Africa.

MyBroadband Insights tracked indicators such as Call Setup Success Ratio (CSSR), Dropped Call Ratio (DCR), Call Setup Time (CST), and Speech Quality Mean Opinion Score (MOS).

After the testing, the results were collated according to the globally recognised European Telecommunications Standards Institute (ETSI) specifications.

The testing was done in partnership with Keysight distributor Coral-I and used Keysight’s network testing platform, Nemo.

It is the global standard in network quality testing, ensuring that MyBroadband’s testing was in par with the best in the world.

The voice network quality scores revealed that Vodacom was a joint-winner of the MyBroadband Best Voice Network in South Africa award.

The research also found that Vodacom boasted the fastest call setup time among major mobile networks — at only 1.51 seconds.

This refers to the time between when a call is first initiated, and when it registers on the receiving device.

The longer the call setup time, the longer callers must wait before they hear the dialling tone — resulting in increased user frustration.

By keeping its call setup time lower than any other voice network, Vodacom has improved the user experience for its voice customers.

The 2024 voice network quality testing results substantiated Vodacom’s claim of having the most reliable network in South Africa.
