MobiMatter does not provide an unlimited‑data eSIM plan for Guinea‑Bissau. The available options are fixed data plans that supply a set amount of high‑speed data for a fixed validity period. For example, the Best World 50GB 180‑day plan delivers 50GB over six months, and the Best World 10GB plan supplies 10GB for one month. These fixed‑data offerings can be more cost‑effective for most users, while very heavy data consumers may prefer a larger‑cap plan.
