eSIMCard does not provide a truly unlimited high‑speed data plan for Vatican City. All of the plans that carry the word “Unlimited” actually have fixed data caps, such as 1GB or 2GB for the entire validity period, and after the cap is reached the connection is throttled to 500kbps or 2000kbps.
Instead eSIMCard offers a range of fixed‑data eSIMs that may better suit most travelers. For example, a 100GB plan is available for 31 days at $37.63 USD, while a 50GB plan is available for 30 days at $36.87 USD. These plans provide unthrottled high‑speed data and can be more cost‑effective unless a user expects to consume data far beyond the daily limits of the “Unlimited”‑named options.
