Roamic does not provide a truly unlimited data eSIM for Niger.
The plans that carry “Unlimited” in their name actually include a fixed high‑speed data allowance of 3 GB per day (or 3 GB total for the 1‑day option) and, once that amount is reached, the speed is throttled to 1000 kbps. Because of the speed reduction the data is not unlimited.
Travelers who want larger data allowances can choose Roamic’s fixed data plans, such as the 20 GB / 30 days plan for $68.23 USD, the 10 GB / 30 days plan for $46.97 USD, or the 5 GB / 21 days plan for $27.96 USD. These plans offer high‑speed data without the post‑toll‑throttling that characterises the “Unlimited” plans and can be more cost‑effective for heavy data users.
