nextSIM does not provide a truly unlimited high‑speed data eSIM for Namibia.
All plans that carry the label “Unlimited” contain a fixed cap of high‑speed data (for example, 1GB or 2GB) and, after this amount is used, the speed is reduced (to 512 kbps or 2000 kbps).
If a user needs more than the cap, the data will slow down.
Customers who need larger data allowances can choose from the fixed data plans nextSIM offers.
For instance, the eSIM 5GB 30 Days Namibia plan gives 5 GB of full‑speed data for 30 days, and the eSIM 3GB 30 Days Namibia plan gives 3 GB for the same period.
These plans provide a larger total data amount without the post‑cap throttling, making them more economical for moderate to heavy data users.
