eSIMCard does not offer a truly unlimited high‑speed data eSIM for Monaco. All plans that use “Unlimited” in their name contain a fixed data allowance. For example, the “ eSIM Data For 1 Day in Monaco” plan includes 1GB of high‑speed data per day and, after that data is used, the transmission rate drops to 500kbps. The longest “unlimited”‑named option is 10 days, providing 1GB/day of high‑speed data before throttling.
If a higher data allowance is preferred, eSIMCard provides fixed‑data plans such as the 50GB data plan valid for 30 days at $31.39 USD or the 35GB data plan also valid for 30 days at $31.39 USD. These plans offer large amounts of high‑speed data without throttling, although they are not truly unlimited. Choosing a fixed‑data plan can be more cost‑effective for travelers who expect high data usage.
