Kolet does not provide a truly unlimited high‑speed eSIM for Belgium. The plans that carry “UNLIMITED” in the name give up to 5GB per day at full speed and then throttle to 1024 kbps. After the daily limit is reached the data remains usable but the speed is reduced.
Travelers who need a larger data allowance may choose one of Kolet’s fixed‑data plans, such as the 20GB for 365 days or the 10GB for 365 days offers, which provide a set amount of data for a long validity period without the daily throttling that applies to the “UNLIMITED” plans.
