NiftySIM does not provide an unlimited data eSIM plan for Eswatini (Swaziland). All of the listed plans have a fixed data cap, such as 20GB for 30 days or 20GB for 90 days, and the data allowance is limited to the specified amount.
If a traveler needs a large data allowance, NiftySIM offers fixed data plans that can be suitable. For example, the “Global 20GB 30 days” plan gives 20GB of data for 30 days, and the “Global 20GB 90 days” plan provides the same amount of data for 90 days. These fixed plans can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer who would require an unlimited option.
