simpleSIM does not provide an unlimited‑data eSIM specifically for Guinea‑Bissau. The provider’s offerings for the country are fixed data plans that have a hard data cap and a set validity period.
For example, the eSIM Guinea‑Bissau 20GB + Calls & Texts plan provides 20GB of high‑speed data and is usable for 30 days from first use. A second option is the eSIM Guinea‑Bissau 10GB plan with the same 30‑day validity. These fixed plans can be more cost‑effective for most travelers, especially those who are not extremely heavy data consumers.
