nextSIM eSIM Data Plans for South Africa

NextSIM does not provide a truly unlimited data eSIM for South Africa. The plans that carry the “Unlimited” label give a fixed amount of high‑speed data—either 1GB or 2GB depending on the plan’s validity—and once that amount is exceeded the speed is reduced to 512 kbps or 2000 kbps. This differs from a genuine unlimited high‑speed bundle.

If you require more data, nextSIM offers substantial fixed‑data alternatives. For example, a 100GB plan lasts 30 days, and a 50GB plan also has a 30‑day validity. Both of these plans keep high‑speed 3G, 4G, or 5G connectivity for the entire period without throttling.

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 provides 28 single‑country data plans for South Africa, while it does not offer any multi‑country plans that include the country. The available plans cover a data range from 1 GB up to 100 GB and a price range from about $4.27 to $1, 264.60. Validity periods vary from one day to one year. The catalog includes both daily‑cap plans—often suited for short‑term travelers—and fixed‑cap plans—ideal for those who want a set amount of data for a longer stay.
