Trifa does not offer an unlimited data eSIM plan for Zambia. The available plans are fixed data packages, each providing a limited data allowance, such as the 100GB plans valid for 3 days, 5 days, 7 days, 10 days, or 15 days. Travelers who need a larger amount of data can choose one of these fixed plans; for example, the 100GB/5d or 100GB/10d options provide substantial data capacity for a set validity period. Choosing a fixed data plan can be more cost‑effective unless a user requires nonstop data usage beyond the plan’s cap.
