simpleSIM does not provide any unlimited‑data eSIM plan for Nigeria. All of its plans for the country come with a fixed data allowance that must be used within a set validity period. For example, the eSIM Nigeria 20GB plan offers 20GB of data for 30 days, and the eSIM Worldwide 20GB plan provides 20GB for 30 days (or 365 days on a different variant). Travelers who need large amounts of data can select one of these fixed data plans, which may be more cost‑effective than a pay‑as‑you‑go option unless they are extremely heavy data users.
