Billion Connect eSIM Data Plans for San Marino

Billion Connect does not provide an unlimited data eSIM for San Marino. All plans available for the country have fixed data caps. Travelers may choose from several fixed‑data options, such as a 100GB plan valid for 30 days priced at $54.99 USD, a 50GB plan for 30 days at $29.99 USD, or a 20GB plan for 30 days at $19.99 USD.

Choosing a fixed‑data plan can be a more cost‑effective approach unless the traveler expects to consume a very large amount of data. Fixed plans offer clear pricing and predictable data limits, helping travelers avoid unexpected charges while still keeping high‑speed network access in San Marino.

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 three multi‑country plans that include San Marino. The plans range in price from $19.99 to $54.99 and provide between 20 GB and 100 GB of data for a 30‑day validity period. All multi‑country options allow tethering and enforce a reduced speed of 128 kbit/s once the data cap is reached.
