RedEx eSIM does not provide a truly unlimited data plan for Vatican City. Every plan shown in the dataset has a specified data cap, even when the name contains the word “Unlimited.” The largest data allowance available is a 200 GB plan that is usable for 30 days, and another fixed 100 GB plan also for 30 days. In addition, there are shorter daily or multi‑day packages that give 2 GB or 3 GB per day; after the allotted amount the speed is reduced, so those are not unlimited either. Choosing one of these fixed‑data plans will give you a large, predictable data supply, but none of them are unlimited.
