CloudOn eSIM does not provide a truly unlimited high‑speed data plan for Nigeria. Some of the plans that carry the word “unlimited” in their name actually offer a fixed high‑speed allowance of 2 GB per day; once that threshold is reached the speed is throttled to 1 Mbps. Because of this throttling, the plans are not considered unlimited.
Instead, CloudOn offers fixed‑data plans for travellers in Nigeria. For example, the Nigeria_20GB_30DAYs plan gives 20 GB of high‑speed data valid for 30 days, and the Nigeria_10GB_30DAYs and Nigeria_5GB_30DAYs plans provide 10 GB and 5 GB respectively within the same validity period. These fixed‑data options are often more cost‑effective for regular data users who do not need an unlimited package.
