nextSIM does not provide a truly unlimited high‑speed data plan for Vatican City. The plans that carry the words “Unlimited” deliver a fixed amount of high‑speed data each day – 1 GB or 2 GB – and once that limit is reached the internet speed is throttled to a reduced rate of either 512kbps or 2000kbps.
Travelers who need a larger, unrestricted data allowance can choose one of nextSIM’s fixed‑data packages, such as the 50GB 30 days plan at $33.83 USD, the 20GB 30 days plan at $15.43 USD, or the 10GB 30 days plan at $9.06 USD. These options are often more economical for heavy data users who do not want to deal with speed reductions after a daily cap.
