gosimless does not provide an unlimited data eSIM for Monaco. The provider offers only fixed data plans with specific data caps and validity periods. Examples include the Monaco 20GB – 30 days plan at $325.99 USD, the Monaco 10GB – 30 days plan for $168.49 USD, the Monaco 5GB – 30 days plan priced at $92.49 USD, and the Monaco 3GB – 15 days and 30 days plans at $55.49 USD and $59.49 USD, respectively.
Choosing one of these fixed data options is usually more cost‑effective unless a traveler expects to consume data beyond the plan’s cap. Each plan is active only for the stated validity and does not offer unlimited usage.
