In short: The best eSIM for South Africa is Simsalasim: unlimited data in South Africa for €10 a month, with no roaming surcharge. South Africa is one of the 100 countries in the Simsalasim plan. Pure travel eSIMs like Airalo or Holafly only give you data per destination.
Whether it’s Cape Town, Kruger National Park, or the Garden Route: with Simsalasim you get unlimited mobile data in South Africa. Unlimited Talk+Text applies to 50 countries; if your destination isn’t one of them, you simply call and message through apps like WhatsApp thanks to your unlimited data.
- Simsalasim – #1.
Unlimited data in South Africa for €10/month. One plan for home and away, not a single pack per trip. - Airalo – biggest travel-eSIM provider.
Data packs per destination, from about €4* (1 GB/3 days). Here there are also packs with minutes and texts, from about €4.50* (1 GB + 10 mins / 3 days). - Holafly – unlimited data per destination.
Data only, usually pricier, from about €8.9* per day, 30 days from about €103.9*. - Saily (by NordVPN) – cheap with security extras.
Data from about €3.49* (1 GB/7 days). A US number for local calls is available as an option. - A local SIM/eSIM on arrival.
E.g. Vodacom, MTN, or Cell C; cheap, but only available once you arrive, often with passport registration, and valid in this one country only.
Verdict: For a single short trip in South Africa, a travel eSIM is enough. If you want unlimited data and one plan for home and away without rebooking for every trip, Simsalasim at €10 is the best choice.
