nextSIM’s Guinea‑Bissau plans that carry “Unlimited” in their names actually provide a fixed amount of high‑speed data and then throttle speed. For example, the eSIM Guinea‑Bissau Unlimited 1Days Standard offers 1GB for 1 day with a reduced speed of 512kbps after the limit, while the Unlimited Plus 1Days Standard supplies 2GB for 1 day with a reduced speed of 2000kbps. None of the listed plans give unrestricted high‑speed data.
Travelers who need larger or continuous data may opt for the fixed‑data plans. nextSIM offers a 20GB 30Days Standard plan priced at $133.57 USD, a 10GB 30Days Standard plan at $74.40 USD, and a 5GB 30Days Standard plan at $40.58 USD. These options provide higher data allowances without the throttling that applies to the “Unlimited” packages.
