eSIMCard’s plans with “Unlimited” in the name are actually limited‑data packages. Each plan provides a fixed amount of high‑speed data—such as 1GB per day or 2GB per day for the 1‑ or 3‑day packages—and once that limit is reached, the speed drops to a reduced rate (e.g., 512 kbps or 2000 kbps). None of the New Caledonia offerings give unlimited high‑speed data, so if true unlimited use is needed, the user would need to upgrade a plan or purchase additional data.
Fixed data plans are available as alternatives. For example, the 10GB plan valid for 7 days costs $203.51 USD, and the 5GB plan valid for 7 days costs $113.28 USD. These options provide a larger single allowance and may be more cost‑effective for travelers who use a lot of data, while still keeping the connection fully fast until the limit is reached.
