Bordersim does not provide an unlimited data eSIM for Vatican City. The available options are fixed data plans that include 100GB for 180 days, 50GB for 90 days, 20GB for 30 days, and 10GB for 30 days, all of which support 5G connectivity in Vatican City.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from a pay‑as‑you‑go model.
