Ovosim does not provide a true unlimited data eSIM for Belgium. All plans that carry “Unlimited” in their title actually contain a defined high‑speed data quota that is limited per day or per validity period, such as the EUconnect Unlimited 10‑day plan, which offers 7 GB/day for 10 days, or the EU 120 GB Unlimited Calls plan, which gives 4 GB/day over 30 days.
Travelers who need more data can choose fixed‑data plans. For example, the EU 120 GB Unlimited Calls plan delivers 120 GB of high‑speed data for 30 days, while the Half Global 120 GB Yearly plan supplies 123 GB for a full year. These plans give a large data allowance and may be more cost‑effective unless the user is an extremely heavy data consumer.
