eSIMCard does not offer a true unlimited data eSIM for Cape Verde. All plans that carry the “Unlimited” name in the catalogue actually provide a fixed amount of high‑speed data—1 GB for the 1‑day and 3‑, 5‑, 7‑, 10‑day plans, or 2 GB for the “Unlimited Plus” options. Once the cap is reached the speed is reduced to 512 kbps for the 1 GB plans or 2000 kbps for the 2 GB plans.
If a traveler needs more data without the speed reduction, eSIMCard offers several fixed‑data alternatives. For example, a 10 GB plan is available for 7 days, 15 days, or 30 days, and a 5 GB plan is available for 7 days or 15 days, both with full high‑speed data during the validity period. These plans are typically more cost‑effective for moderate to heavy data users.
