Nomad does not provide a truly unlimited data eSIM for San Marrino. The plans that carry “unlimited” in their name actually deliver a daily allowance of 2GB over 5 or 10 days, after which the speed is reduced to 1000 kbps.
Travelers looking for larger data allowances can choose from fixed data plans such as a 50GB bundle for 30 days, priced between $35 and $39 USD, or a 20GB bundle for 30 days, priced between $20 and $27 USD, all of which deliver high‑speed 5G data throughout the validity period without speed throttling.
