The average download speed in South Africa is 28.62 Mbps, which is above the global average of 20.18 Mbps. However, there is a significant difference in internet speed between urban and rural areas. In urban areas, the average download speed is 42.14 Mbps, while in rural areas, the average download speed is only 13.39 Mbps.

The fastest mobile internet in South Africa is 5G, which can reach speeds of up to 20 Gbps download and 10 Gbps upload. However, 5G is still in its early stages of development in South Africa, and coverage is not yet widespread. As a result, the fastest mobile internet for most users in South Africa is still 4G LTE, which can reach speeds of up to 100 Mbps download and 50 Mbps upload.

Here are some of the factors that affect internet speed in South Africa:

• Location: The location of the user can have a significant impact on internet speed. Users who are located in urban areas will typically have faster internet speeds than users who are located in rural areas.
• Network congestion: Network congestion can also affect internet speed. When there are too many users on a network, it can slow down the speeds for everyone.
• Device: The type of device being used can also affect internet speed. Older devices may not be able to support the latest internet speeds.
• Plan: The internet plan that a user has can also affect internet speed. Plans with higher data caps typically have faster speeds.

Overall, internet speed in South Africa is good, but there are some areas where it could be improved. As the country continues to develop, it is likely that internet quality and affordability will improve.
