MobiMatter does not provide an unlimited data eSIM for Vatican City. All of its plans for the destination are fixed‑data plans that grant a specific amount of data over a set validity period. For example, the Europe 60 GB plan gives 60 GB for 15 days, and the Europe and USA 60 GB 60 days plan offers 60 GB for 60 days, both with tethering allowed. Because unlimited data is not available, travelers who expect heavy usage may find one of these fixed‑data options more cost‑effective than a pay‑as‑you‑go plan unless they are extremely heavy consumers.
