WonderConnect does not provide any unlimited data eSIM for Nigeria.
The provider offers fixed‑data plans such as 50 GB for 30 days at $106.39 USD and 20 GB for 30 days at $48.99 USD, both featuring tethering and usable within the 30‑day validity period.
Choosing a fixed‑data plan can be more cost effective than buying pay‑as‑you‑go credit for most travelers, unless a user expects to consume very large amounts of data beyond the available bundle.
