Billion Connect eSIM Data Plans for San Marino

Billion Connect does not offer an unlimited data eSIM plan for San Marino. The available options provide specific data caps, such as 100 GB and 50 GB for a 30‑day period, or 20 GB for 30 days or 1 day. These fixed‑data plans give travelers predictable bandwidth and are often more cost‑effective than a hypothetical unlimited package, especially for users who do not require very heavy data consumption.

Billion Connect does not provide an eSIM for San Marino that includes a phone number or SMS capability. Only data‑only eSIM plans are available from this provider. Travelers can still use VoIP services such as WhatsApp, Telegram and iMessage over the data connection for voice and messaging, but no traditional phone number or SMS service is offered.

Billion Connect offers four multi‑country data plans that include coverage in San Marino. The plans vary in price from $19.99 to $54.99 and provide data caps between 20 GB and 100 GB. All plans feature a fixed data allowance, with tethering allowed and a reduced speed of 128 kbps that may apply. No single‑country plans are available for San Marino.
