NiftySIM does not provide an unlimited data eSIM for New Caledonia. The available options are fixed data plans that must be used within a set validity period. For example, NiftySIM offers a 20GB plan valid for 30 days, a 10GB plan also valid for 30 days, a 5GB plan for 30 days, a 3GB plan for 15 days, and a 3GB plan for 30 days. These plans give travelers a clear data allowance and a defined period in which the data can be used. Choosing a fixed data plan can be more cost‑effective for most users, unless a traveler expects to consume data at a very high rate that would exceed the available bundles.
