AlpineSIM does not provide a true unlimited data eSIM for travelers in Zambia. All plans listed under the “Unlimited” heading contain a specified data cap, such as 500 MB/day, 1 GB/day, 10 GB/day, or larger flat‑rate packages that are valid for a set period. When the cap is reached the data speed typically drops to a lower, throttled rate, although the exact reduced speed is not disclosed in the available information.
Travelers who need more data can choose one of AlpineSIM’s fixed‑data options, such as the 10 GB/day plan valid for one day, or the 20 GB plan valid for 30 days. These higher‑capacity packages offer a larger high‑speed data allowance and may be more cost‑effective for heavy usage compared with the capped “unlimited” plans.
