eSIMsData does not provide a true unlimited data eSIM for Zambia. All of its plans that contain the word “Unlimited” in the name have a hard daily high‑speed allowance—either 1 GB or 2 GB per day—after which the speed is throttled to 1250 kbps or 2000 kbps.
For travelers who need more data, eSIMsData offers fixed‑data plans such as the 20 GB 30‑day plan for Zambia, priced at $120.44 USD, or the 10 GB 30‑day plan for $69.89 USD. These plans provide a larger, capped amount of high‑speed data within a set validity period and can be more cost‑effective for heavy data users.
