Astaroam eSIM Data Plans for South Africa

Astaroam does not provide a truly unlimited data eSIM for South Africa. The plans that are labelled “Unlimited” give 3 GB per day, and once that cap is reached the data speed is reduced to 1000 kbps.

Instead, Astaroam offers fixed‑data options that cover South Africa. For example, a 20 GB plan for 30 days costs $26.33 USD, and a 10 GB plan for 30 days costs $13.35 USD. These plans give full high‑speed data without any daily limit, and choosing a fixed‑data plan can be more cost‑effective unless a traveler needs an extremely high volume of data.

Astaroam does not provide an eSIM plan for South Africa that includes a local phone number or SMS capability. The available offering is data‑only, so travelers must rely on the internet connection for communication.

Because the plan lacks a phone number, calls and messages are typically made through VoIP applications such as WhatsApp, Telegram, or iMessage. Those apps usually work over a data connection, but some destinations block or restrict access to specific services. Travelers should verify that the applications they rely on are accessible in South Africa before purchasing the eSIM.

Astaroam offers 10 single‑country plans and 6 multi‑country plans that include South Africa. The available plans range from about $2.38 to $28.01, with data caps from 1 GB up to 20 GB. Within this offering, some plans provide a fixed data amount while others impose a daily data cap, giving users flexible options to match their usage patterns.
