MyTravel eSIM does not provide an unlimited data eSIM for South Africa. The available plans for the country are fixed data bundles, such as the South Africa 20GB 30Days plan, the South Africa 10GB 30Days plan, and the South Africa 5GB 30Days plan, each with a 30‑day validity period.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from an unlimited option.
