NextSIM does not have a true unlimited data eSIM for South Africa. All plans that include “Unlimited” in the name are actually fixed‑data packages that offer a set amount of high‑speed data each day—for example, the eSIM Unlimited Standard 1 Day South Africa gives 1GB per day and reduces speed to 512kbps once the limit is reached, while the eSIM Unlimited Plus 1 Day South Africa provides 2GB per day and throttles to 2000kbps afterward.
Travelers who need a larger, unrestricted data allowance can choose from the fixed data plans that nextSIM offers for South Africa. For instance, the eSIM 100GB 30 days South Africa plan provides 100GB of high‑speed data for 30 days, and the eSIM 50GB 30 days South Africa plan offers 50GB for the same period. These fixed plans may be more cost‑effective for users who consume a lot of data without needing the unlimited labeling.
