MobileSIM eSIM Data Plans for South Africa

MobileSIM does not provide a true unlimited data eSIM for South Africa. The plans that carry “Unlimited” in the name give 3 GB per day and, after that limit is reached, throttle the speed to 1000 kbps. Travelers can instead choose from fixed data options; for example, a Global 20 GB plan that lasts 365 days costs $69.00 USD, and a Global 10 GB plan for 180 days costs $59.00 USD. These examples show the large data allowances available and illustrate that a fixed data plan may be more cost‑effective than a plan that is limited by speed after a daily cap.

MobileSIM does not provide an eSIM plan for South Africa that includes a phone number or SMS capability. All available plans from this provider are data‑only, meaning they allow internet access but do not support inbound or outbound voice calls or text messages.

Travelers who need to keep in touch can use VoIP applications such as WhatsApp, Telegram or iMessage, which operate over the data connection and provide messaging and call functionality without requiring a local phone number or SMS service.

MobileSIM offers five single‑country plans and ten multi‑country plans for South Africa. The available options span a price range from about $1.50 to $69.00 and a data cap range from 200 MB up to 20 GB. Plans are offered in two main formats: fixed data caps, where a set amount of data is available for the full validity period, and daily data‑cap plans, which limit the amount of data that can be used each day while the contract remains active.
