MobiMatter does not provide an unlimited data eSIM for Monaco. All of its Monaco‑specific plans have a hard data cap listed in the Data cap column – for example, the Monaco 10GB plan for 30 days, the Monaco 5GB plan for 30 days, or the larger Best World 50GB plan for 180 days. Because each plan must be used within its validity window, they are fixed data plans rather than pay‑as‑you‑go offerings.
For travelers who need more data than a single fixed bundle offers, MobiMatter’s larger 50GB plan may be the most economical choice, but it still imposes a 50GB limit. If a truly unlimited data experience is required, a different provider would need to be considered.
