There is no truly unlimited high‑speed data eSIM from nextSIM for Guinea‑Bissau. nextSIM’s plans that carry “Unlimited” in the name actually cap data to a fixed amount and slow the speed when the limit is reached – for example, the eSIM Guinea‑Bissau Unlimited 1Days Standard gives 1GB of fast data and reduces speed to 512kbps thereafter, while the Unlimited Plus variant supplies 2GB before throttling to 2000kbps.
Travelers who need more data can choose from the fixed‑data options, such as the 20GB 30Days Standard plan or the 10GB 30Days Standard plan, which provide larger bundles at a set price and are typically more cost‑effective unless the user requires a very high data volume.
