Simbye does not provide a truly unlimited high‑speed data eSIM for San Marino. The plans that carry the word “Unlimited” in their name give 2 GB per day at full speed and then allow unlimited use at a reduced speed of 1 Mbps.
Travelers who need more data can choose from Simbye’s fixed data plans, such as the Europe Orange Holiday 100 GB, 50 GB, or 20 GB options, each valid for 30 days. These plans offer large data allowances at full speed and can be more cost‑effective for most users unless a very heavy data consumer requires a truly unlimited plan.
