eSIMCard does not provide a truly unlimited data eSIM for South Africa. All of its South African plans have a fixed data allowance, such as 1 GB per day or 2 GB per day on the “Unlimited”‑named packages, or 25 GB, 50 GB, and 100 GB on other bundles. When the stated data cap is reached the network speed is throttled to 512 kbps or 2000 kbps, so the plan is not unlimited in the sense of unlimited high‑speed data.
If a user needs a larger allowance, eSIMCard offers fixed data plans as options. For example, the Vodafone 25 GB Data plan lasts 30 days and the Orange 50 GB and 100 GB plans last 31 days, providing a larger data capacity at a fixed price. Choosing a fixed‑data plan can be more cost‑effective for travelers who do not need continuous unlimited usage.
