BNESIM does not provide a true unlimited‑data eSIM for travelers in Guinea‑Bissau. All available plans list a fixed data cap, the largest being 20 GB, and there is no plan that offers an unlimited data allowance.
Travelers who need a large amount of data can choose from the fixed‑data options supplied by BNESIM. For example, the 20 GB plan for 30 days costs $329.33 USD and the 10 GB plan for 30 days costs $168.42 USD. Selecting a fixed‑data plan is typically more economical unless a user requires a very high volume of data, in which case exploring other providers might be worthwhile.
