RedEx eSIM does not provide a true unlimited data eSIM for San Marino. All of the plans listed for this destination have a specified data cap, ranging from a few gigabytes per day to several hundred gigabytes over a month or longer. The “Unlimited Data” label in the plan names refers to the fact that the data is not throttled after the cap is reached; instead, the speed is reduced to a lower level (for example, 512 kbps or 1000 kbps) once the allocated amount is used.
If a traveler needs a large amount of high‑speed data, RedEx eSIM offers fixed data plans such as the 100 GB, 200 GB, or 512 GB options that are valid for 30 or 90 days. These plans provide a substantial data allowance and include tethering, but they are not unlimited. Travelers who require truly unlimited data would need to look at other providers.
