NextSIM does not offer a true unlimited data eSIM for Vatican City, as all of its plans have a capped amount of high‑speed data. Each plan listed carries either 1 GB per day, 2 GB per day or a total of 2 GB for the entire validity period, after which the connection speed is reduced to the specified throttled rate.
If you need more data without the speed reduction, you can choose one of the fixed‑data options that are available, such as the 2 GB plan valid for 15 days or the 1 GB/day plans that run for 1 to 30 days. Fixed‑data plans often provide a simpler, cost‑effective solution unless you are an exceptionally heavy data user who requires uninterrupted high‑speed access.
