ChillaxSIM does not offer a truly unlimited data eSIM for Italy. The plans marked “unlimited” actually provide 1 GB of high‑speed data per day (e.g., Italy unlimited data for 3‑30 days), and once that daily limit is reached the speed drops to 5120 kbps.
Instead, ChillaxSIM and its partners sell fixed data plans that give a larger, capped allowance. For example, the “Italy Total 50GB for 30 days” plan gives 50 GB of high‑speed data for 30 days with a reduced speed of 128 kbps after the 50 GB is used, and the “Orange Europe (51 countries) Total 100GB” plan offers 100 GB for 30 days with the same 128 kbps throttling once the data cap is reached. These fixed‑data options tend to be more cost‑effective unless a user requires a very large amount of high‑speed data.
