Billion Connect eSIM Data Plans for San Marino

Billion Connect does not currently offer an unlimited data eSIM for San Marrino. Their available plans for the country are fixed‑data options, the largest of which is a 100GB plan that costs $54.99 USD and is valid for 30 days. Other plans include 50GB for $29.99 USD and 20GB for $19.99 USD, all of which provide 5G connectivity to San Marrino and 40 additional European countries. If you need a large amount of data, choosing one of these fixed‑data plans may be more cost effective than looking for an unlimited option.

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.
