simpleSIM does not provide a truly unlimited data eSIM for Vatican City. The plans that carry the “Unlimited” label offer a hard cap of 1 GB per day and, after the limit is reached, the speed is throttled to 1000 kbps. If a traveler needs more data, simpleSIM offers fixed‑data plans with larger allowances. For example, the eSIM Vatican 20GB plan delivers 20 GB of high‑speed data usable for 30 days, and the eSIM Vatican 10GB plan gives 10 GB for the same period. These fixed‑data options can be more cost‑effective for most users who need a substantial amount of data while traveling in Vatican City.
