MeSIM 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. Examples include the New Caledonia 20GB 30Days plan, the New Caledonia 10GB 30Days plan, and the New Caledonia 5GB 30Days plan, each offering a specific data allowance for 30 days. For travelers who need data on a daily basis, MeSIM also offers the New Caledonia 10GB/Day and New Caledonia 5GB/Day plans, which provide the stated amount of data for one day each. Choosing a fixed data plan can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer.
