There are no unlimited data eSIM plans for Guinea‑Bissau sold by eSIM‑On Shop. The only plans offer a fixed data allowance, such as 5GB for 30 days at $44.00 USD, 3GB for 15 days at $28.00 USD, and 1GB for 7 days at $12.00 USD. These examples illustrate some of the larger data options available while showing that the current selection is limited to fixed‑cap plans only.
Choosing a fixed data plan can be cost‑effective for most travelers, especially those who use a moderate amount of data. If you expect to consume data at a very high rate, a fixed plan may become more expensive compared to a truly unlimited alternative, which is currently not offered by this provider for Guinea‑Bissau.
