South African networks see the worst 4G signal strength but fastest 4G download speeds at night

Posted: May 25, 2023

Opensignal analyzed how energy usage changes on South African networks throughout the day. We observe that South African operators use less spectrum and carrier bands at night, while the 4G signal strength is also the weakest at night. For the purpose of the analysis, we focus on 4G metrics, as only MTN and Vodacom have launched commercial mobile 5G services in South Africa.

But in our new video experience analysis, MTN didn't have to settle for second in the awards table: it scored a narrow win over Vodacom in our overall video experience measurements.
