Astaroam does not provide an unlimited data eSIM for Zambia. The available plans are fixed data bundles that must be used within a set validity period. Examples include the Zambia 5GB 30Days plan, the Africa 5GB 30Days plan that covers Zambia and 28 additional countries, and the Zambia 3GB 30Days plan. These plans offer a specific data allowance that expires after the stated number of days.
Choosing a fixed data plan can be more cost‑effective for most travelers, especially those who do not consume data at a very high rate. If a user requires continuous, unlimited data usage, they would need to purchase additional data credits or consider a different provider that offers a true unlimited plan.
