Yes, an eSIM Scout plan, leveraging top US carriers like AT&T or T-Mobile, provides extensive coverage across the Hawaiian islands. You'll maintain connectivity in major population centers, popular tourist sites, and many less-populated areas on Oahu, Maui, Kauai, and the Big Island. However, extremely remote or mountainous terrain may present signal challenges, as is common with any mobile network. Always check the coverage maps for your specific operational area.
