eSIMCard does not provide any truly unlimited data eSIM plans for San Marino. All of the available offerings list a fixed data allowance, such as 50GB or 35GB for a 30‑day validity, or 53.69GB for 60 days. Plans whose names contain the word “Unlimited” still have a defined data cap and do not give unlimited high‑speed data; after the cap is reached, the speed is reduced to the network’s standard rate.
Travelers who need a large amount of data can choose from the fixed‑data options. For example, a 50GB plan is available for 30 days at $31.39 USD, while a higher‑capacity 53.69GB plan is offered for 60 days at $255.60 USD. These plans provide a cost‑effective alternative for users who expect to use a substantial but not unlimited amount of data during their stay in San Marino.
