Astaroam eSIM Data Plans for South Africa

Astaroam does not provide an unlimited data eSIM for South Africa. All of its South Africa plans have a fixed data cap, such as 20GB, 10GB, 5GB, or 3GB, each with a validity period of 30 days or 15 days.

Travelers who need a larger data allowance can choose from Astaroam’s fixed data plans. For example, the South Africa 20GB 30Days plan and the South Africa 10GB 30Days plan offer substantial data limits and may be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer.

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 seven single‑country data plans and six multi‑country plans that cover South Africa. The plans range in price from $2.42 to $27.02 and provide data caps between 1 GB and 20 GB, with validity periods of 7 to 30 days. Some of the available options include tethering.
