MobileSIM does not provide a truly unlimited data eSIM for Belgium. The plans that are labeled “Unlimited” in the name, such as Belgium Unlimited data for 10 days, actually offer 3 GB of high‑speed data per day and switch to a reduced speed of 1000 kbps after that limit is reached, so they are not unlimited in the strict sense.
Travelers who need larger data allowances can choose from the fixed‑data plans that MobileSIM offers for Belgium. One example is the Belgium 20 GB for 30 days plan, which delivers 20 GB of high‑speed data over 30 days. Another option is the Europe 50 GB for 30 days plan, which gives 50 GB across Belgium and other European countries for 30 days. These fixed plans are often more cost‑effective unless a user requires a very large amount of data with no speed throttling.
