4S eSIM eSIM Data Plans for Monaco

4S eSIM does not provide a truly unlimited high‑speed data plan for Monaco. All plans that carry the word “Unlimited” in their name actually contain a fixed data cap and, after that threshold is reached, the connection speed is throttled to 1000 kbps. Therefore, customers looking for unrestricted data would need to choose one of the fixed data plans, such as the 10 GB plans valid for 5, 7, 15, 30, or 90 days, which offer a larger data allowance without automatic speed reduction.

4S eSIM does not provide a Monaco eSIM that includes a phone number or SMS capability; only data‑only plans are offered. Because the service lacks inbound or outbound call and SMS features, travelers cannot rely on a local phone number for communication while in Monaco.

For voice and messaging, users can turn to VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so travelers are advised to confirm that the apps they depend on are functional in Monaco before purchasing a plan.

4S eSIM offers 26 single‐country data plans for Monaco. These plans include 22 fixed cap options and 4 daily cap options. Prices for the available plans range from about $16.46 to $231.40, while data caps vary from 714 MB up to 10 GB. Fixed cap plans give a set amount of data that can be used at any time during the validity period, whereas daily cap plans limit the amount of data that can be consumed each day, resetting the allowance at the start of each new day.
