Ubigi does not offer a truly unlimited data eSIM plan for Zambia. The available plans are fixed‑data bundles that must be used within a set validity period.
For travelers who need large amounts of data, Ubigi provides fixed data plans such as the BEST WORLD 200GB bundle for $290.00 USD, valid for 360 days, and the BEST AFRICA 100GB bundle for $140.00 USD, also valid for 360 days. These bundles are the most generous options for Zambia, and a traveler who uses more data than the bundle allows can top up additional credit.
