RedEx eSIM does not provide an unlimited data eSIM for travel to Monaco. All of the plans that are available for Monaco list specific data caps. The largest fixed‑data option is the 200 GB plan, which is valid for 30 days, and there are also 100 GB, 50 GB, 30 GB, and 20 GB plans with the same 30‑day validity. If a traveler needs a very high amount of data, a fixed data plan such as the 200 GB or 100 GB bundle may be a suitable choice, and these options are generally cost‑effective for most users unless they require truly unlimited usage.
