eSimfly does not provide a truly unlimited high‑speed data eSIM for Vatican City. All its Vatican City plans have a fixed data allowance, the largest of which is 120GB and the others 60GB, 35GB, or 30GB, each valid for 30 days. The plan names that include “Unlimited” are merely marketing labels; the data cap still limits the amount of high‑speed data available before the connection may be throttled.
For travelers who need a large amount of data without a hard expiry, eSimfly offers fixed data plans such as the Bouygues Telecom 120 GB plan for 30 days or the O2 Unlimited (International) plan with 35 GB for 30 days, both of which include tethering. These fixed‑data options are generally more cost‑effective than a truly unlimited plan, which eSimfly does not currently offer for Vatican City.
