Roamingo does not provide any true unlimited data eSIM for Vatican City. The plans listed carry fixed data caps, the largest being 20 GB for 30 days. A plan titled “Europe Unlimited for 1 day” appears with a name that suggests unlimited use, but its data cap is only 2 GB and therefore is not truly unlimited.
Travelers can choose from a range of fixed‑data options. For example, a 20 GB plan is available for 30 days at $21.00 USD, while a 10 GB plan costs $12.00 USD for the same period. These larger data allowance plans can be more cost‑effective for moderate to heavy data users compared to low‑cost daily plans, but they still impose a clear high‑speed data limit.
