Roamingo does not provide a truly unlimited data eSIM for Belgium. The plans that carry the word “Unlimited” in their name actually offer a 2GB cap per day (or 2GB total for the 1‑day option) and the speed is reduced once that limit is reached, so the data is not unlimited.
Instead, Roamingo offers fixed data plans that give larger, hard‑limit allowances. For example, a 20GB plan for 30 days costs $25.50 USD, a 10GB plan for 30 days costs $14.50 USD, a 5GB plan for 30 days costs $7.50 USD, and a 3GB plan for 30 days costs $7.00 USD. These fixed data plans can be more cost‑effective for most travelers unless they need very high data usage.
