Lumbus does not provide a true unlimited data eSIM for Niger.
Their “Niger Unlimited” plans give only 3GB of high‑speed data per day; after that usage the speed throttles to 1000kbps, and the name “Unlimited” does not reflect an uncapped allowance.
For travelers who need more data, Lumbus offers fixed‑data alternatives such as the 20GB plan valid for 30 days or the 10GB plan also valid for 30 days. Both provide higher total data allowances while maintaining the same high‑speed network characteristics, and can be a more cost‑effective choice unless a user is a heavy data consumer.
