simpleSIM does not offer any unlimited data eSIM plans for Dominica. The provider’s catalog lists only fixed‑data plans with a 30‑day validity. For example, the eSIM Worldwide 20GB plan supplies 20GB for 30 days, the eSIM Worldwide 10GB plan supplies 10GB for 30 days, and the eSIM Dominica 5GB plan supplies 5GB for 30 days. Similar 5GB and 10GB options are also available under the eSIM Worldwide and eSIM Caribbean headings. Because these plans provide a set amount of data that must be used within the 30‑day period, they may be more cost‑effective than purchasing a larger unlimited plan would typically allow, especially for average or moderate data users.
