eSIMPhoney does not provide an unlimited data eSIM for South Africa. All plans listed for South Africa have a fixed data cap, the largest being 50GB.
Fixed‑data plans are available with various validity periods; for example, the Africa – 50GB plan allows 50GB of data for 180 days at $160.34 USD, and the Africa – 10GB plan offers 10GB for 30 days at $22.73 USD. These examples illustrate some of the high‑data‑allowance options, though other fixed plans are also offered. Choosing a fixed‑data plan can be more cost‑effective for most travelers, unless one requires genuinely unlimited data.
