Supera link does not provide an unlimited data eSIM for South Africa. The only listings available are fixed‑data plans, such as the 5GB/day offer that can be purchased for 1 to 5 days, ranging from $8.62 to $28.57 USD.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless you are an extremely heavy data user who would prefer a truly unlimited option. The example of a 5‑day 5GB plan illustrates one of the larger data allowances available, but Supera link’s catalog contains many other fixed‑data options.
