eSimfly does not provide an unlimited data eSIM for Zambia. The provider’s offerings are fixed data plans with explicit limits. For example, Zambia 5 GB 30 days delivers five gigabytes of high‑speed data for thirty days, while other options include Zambia 3 GB 30 days, Zambia 2 GB 15 days, and Zambia 1 GB 7 days, all of which allow tethering.
Choosing a fixed data plan such as the 5 GB option can be more cost‑effective for most travelers, unless the user expects to use data well beyond the highest available allowance.
