nextSIM eSIM Data Plans for South Africa

NextSIM does not provide a truly unlimited‑data eSIM for South Africa. All plans that contain “Unlimited” in the name actually supply a fixed amount of high‑speed data—such as 1 GB or 2 GB per day—after which the speed is throttled to 512 kbps or 2000 kbps. Therefore, the data allowance is limited rather than truly unlimited.

Travelers expecting a larger data allowance can instead choose from the provider’s fixed data plans. For example, the eSIM GLOBAL 50GB 365‑days Economy plan offers fifty gigabytes of high‑speed data over a full year, and the eSIM South Africa 20GB 30‑days Economy plan supplies twenty gigabytes for a month. These capped plans may provide a more cost‑effective solution for users who need more data than the daily “Unlimited” options allow.

nextSIM does not offer an eSIM with a phone number or SMS capability for South Africa. Its South African eSIMs are data‑only plans.

Travelers can still communicate via VoIP applications. WhatsApp, Telegram, and iMessage work over the data connection provided by the eSIM, allowing calls and messaging without a local phone number.

nextSIM offers a total of 22 single‑country plans and 31 multi‑country plans that include South Africa. The plans range from $4.20 to $1,287.28, with data caps between 1 GB and 50 GB and validity periods from 1 day to 365 days. The catalogue contains both daily data‑cap plans—where the amount of data is reset each day—and fixed data‑cap plans that provide a set amount of data for the duration of the validity period.
