eSIMCard does not offer a truly unlimited data eSIM for Belgium. All of its plans that use “Unlimited” in the name are actually capped at a fixed amount of high‑speed data and then go to a reduced speed after the limit is reached – for example, the “Unlimited Data For 1Day in Belgium, Throttled” plan gives only 1 GB of data at 512 kbps after the 1‑GB limit.
Customers who need a large amount of data at full speed can choose from fixed‑data plans such as the 50 GB plan valid for 30 days or the 35 GB plan also valid for 30 days, both providing high‑speed coverage in Belgium and many other European countries. These fixed‑data plans may be more cost‑effective for users that use a lot of data, as they avoid the speed throttling that applies to the “Unlimited” named plans.
