Bordersim does not offer an unlimited data eSIM plan for Guinea‑Bissau. The provider’s available options for that country are fixed‑data plans; for example, a Guinea‑Bissau 20GB 30‑day plan costs $89.99 USD, and a global 20GB plan with 90‑day validity is priced at $83.49 USD.
A fixed‑data plan can be more cost‑effective for travelers who need substantial data but are not extremely heavy users. If a visitor expects to consume data at a very high rate continuously, they might consider a higher‑capacity plan or a larger data bundle, but none of the Bordersim offerings for Guinea‑Bissau are unlimited.
