YonoSIM eSIM Data Plans for San Marino

YonoSIM does not provide an unlimited‑data eSIM for San Marino. All of its plans list a specific data cap in the “Data cap” column, and none of the available offerings have a hard limit of “unlimited.”

Instead, YonoSIM offers fixed‑data plans that can be purchased for a set period. For example, the “50GB 90‑days” plan gives 50GB of data for 90 days at $61.99 USD, while the “20GB 30‑days” plan provides 20GB for 30 days at $17.99 USD. These alternatives supply large data allowances and can be more cost‑effective for most travelers unless very heavy data usage is expected.

YonoSIM does not provide eSIM plans that include a phone number or SMS capability for San Marrino. Customers can only purchase data‑only eSIMs. For voice and messaging, travelers can generally use VoIP services such as WhatsApp, Telegram and iMessage over the data connection; however, some destinations may restrict certain apps or VoIP traffic, so it is advisable to confirm that the services needed are accessible in San Marrino before purchasing.

YonoSIM offers data plans that cover San Marrino through both single‑country and multi‑country products. In the catalogue there are 41 single‑country plans and 42 multi‑country plans. Prices across all plans range from $1.99 to $201.99, while data caps vary between 1 GB and 50 GB.
