eSIM4Travel does not provide a true unlimited‑data eSIM for South Africa. None of the listed plans have a data cap of “unlimited”; instead the plans named “Unlimited‑3Days‑South Africa” and similar offer 3GB of high‑speed data per day, after which the speed is reduced to 1000kbps. Therefore travelers will encounter a throttled speed once the daily allowance is reached.
Instead, eSIM4Travel offers fixed data plans that can be more cost‑effective for frequent travelers. Examples include the South Africa (Telkom SA) – 20GB/30Days plan, which provides 20GB of unthrottled high‑speed data for 30 days, and the South Africa (Telkom SA) – 10GB/30Days plan, offering 10GB of unthrottled data during the same period. These plans allow unlimited use of the allotted data without daily caps.
