eSIMCard’s plans that are labeled “Unlimited” for Guinea actually provide only a set amount of high‑speed data before the speed is throttled. Each of these plans lists a data cap—such as 1 GB, 2 GB, or 1 GB/day—and includes a reduced speed (500 kbps or 2000 kbps) that applies once the cap is reached. Because the data is not truly unlimited, these offerings do not provide continuous high‑speed data without limits.
If a traveler is looking for a larger, flat data allowance that stays at full speed throughout the validity period, eSIMCard does list fixed‑data plans. For example, the 10 GB eSIM Data for 30 days plan provides 10 GB of high‑speed data for 30 days at $137.16 USD, and the 5 GB eSIM Data for 30 days plan offers 5 GB for the same period at $74.68 USD. These plans do not include a reduced‑speed phase and can be more cost‑effective for heavy data users.
