nextSIM does not provide a truly unlimited data eSIM for Nigeria. All plans that use the “Unlimited” name actually offer a fixed amount of high‑speed data—typically 1GB per day or 2GB per day—and after that amount the speed is reduced to 512kbps or 2000kbps. As a result, users who consume more data than the daily allowance will experience throttling rather than unlimited high‑speed access.
If a larger data allocation is needed, nextSIM offers fixed‑data eSIM plans for Nigeria. For example, a 50GB eSIM valid for 30 days is available, as is a 40GB eSIM also valid for 30 days, both priced at a higher but predictable rate. These fixed‑data options can be more cost‑effective for travelers who anticipate heavy data usage.
