ChillaxSIM does not offer a truly unlimited data eSIM for Belgium. All plans that carry the word “unlimited” in their name actually grant a data cap of 1 GB per day. Once the daily 1 GB threshold is reached, the connection speed is throttled to 5120 kbps, as specified in the plan details for Belgium unlimited data for 3, 5, 7, 10, 15, 20, and 30 days.
For travelers who need more data without a daily cap, ChillaxSIM provides fixed‑data options. Examples include the Orange Europe (51 countries) Total plans, which offer 20 GB, 50 GB, and 100 GB for a 30‑day validity, and the O2 Europe (48 countries) plan that provides 35 GB for 30 days. These fixed‑data plans can be a more cost‑effective choice for heavy data users, especially since the unlimited plans still impose a daily data limit and speed reduction.
