nextSIM does not offer a truly unlimited high‑speed data eSIM for Madagascar. The plans labeled “Unlimited” in the nextSIM catalogue actually provide 1GB or 2GB of high‑speed data, after which the speed is reduced to 512 kbps or 2000 kbps.
For travelers needing more data, nextSIM offers fixed data plans. Examples include the eSIM Global Unlimited 10Days Standard plan, which gives 1 GB per day for 10 days, and the eSIM Global Unlimited Plus 10Days Standard plan, which offers 2 GB per day for 10 days. A larger, longer‑term option is the eSIM Madagascar 20GB 30Days Standard plan, which supplies 20 GB of high‑speed data for 30 days. These fixed plans are often more cost‑effective than the “Unlimited” options for users who need substantial data.
