4S eSIM eSIM Data Plans for Monaco

4S eSIM does not provide a true unlimited data eSIM for Monaco.
The plans that carry the word “Unlimited” in their name are capped between 3 GB and 10 GB; after the cap is reached the speed is reduced to 1000 kbps. Travelers looking for consistent high‑speed data can choose one of the fixed‑data options, such as the 10 GB plan valid for 5, 7, 15, 30, or 90 days, which keeps the full data allowance at full speed for the entire validity period.

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.
