Simbye does not provide a truly unlimited high‑speed data eSIM for Vatican City. The plans that carry “Unlimited” in their name, such as Europe Unlimited 7 Days and Europe Unlimited 15 Days, give 2GB of high‑speed data per day and then throttle the speed to 1 Mbps once that daily allowance is used.
Travelers who need more data can choose from Simbye’s fixed data plans, for example Europe Orange Holiday 100GB, 50GB, or 20GB, each valid for 30 days and offering full‑speed data up to the stated limit. These fixed plans are the available alternatives for high‑speed data in Vatican City.
