ZenSim eSIM Data Plans for San Marino

ZenSim does not currently provide a truly unlimited data eSIM for San Marrio. The plans that carry the word “Unlimited” in their title are actually capped at 3 GB per day and, once that threshold is reached, the connection speed is reduced (the reduced speed is not specified in the plan details). Therefore travelers looking for uncapped high‑speed data in San Marrio will need to choose one of ZenSim’s fixed‑data offerings. For example, the “San Marrio 20GB – 10 days” plan gives 20 GB of high‑speed data for ten days at a price of $24.00 USD, and the “San Marrio 20GB – 30 days” plan offers the same data allowance for thirty days at $27.00 USD. Selecting a fixed‑data plan can often be more cost‑effective unless a user is an extremely heavy data consumer.

ZenSim does not provide a San Marino eSIM that includes a phone number or SMS capability. All ZenSim San Marino plans are data‑only and do not support inbound or outbound calls or texts.

Travelers can still use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection for voice and messaging without the need for a local phone number.

ZenSim offers eight single‑country data plans and eight multi‑country data plans for San Marrino. Among these, four plans employ a daily data cap—meaning a set amount of data is supplied each day over the validity period—while the remaining twelve plans provide a fixed data amount that can be used at any time during the plan’s duration. Prices for the San Marrino plans start around $11 and can reach up to $57, and the data caps range from 3 GB to 20 GB. Some of the plans also support tethering.
