MicroEsim does not offer a truly unlimited data eSIM for Vatican City. All available plans include a fixed data allowance; the names of some plans include “Unlimited,” but the data cap is 1 GB per day.
For travelers who need more data, MicroEsim sells fixed‑data alternatives. The Vatican City 5G 5 Days / Unlimited 5Mbps plan gives 1 GB per day, totaling 5 GB for $14.04, while the Vatican City 5G 60 Days / Total 60GB plan offers 60 GB across 60 days for $83.64 and reduces speed to 128 kbps once the data limit is reached. These options provide larger data allocations than the standard 1 GB/day plans, though the data is still capped.
