eSIMTrends' network mapping shows that eSIMs leveraging major U.S. carriers like AT&T or T-Mobile offer comprehensive 4G LTE and 5G coverage across the main Hawaiian islands: Oahu, Maui, Kauai, and the Big Island. Connectivity is strong in urban centers and popular tourist areas. However, as with any mobile service, very remote or mountainous regions, particularly on the outer edges of islands, may experience reduced signal strength. Travelers should anticipate some variability in these specific, less-populated zones, but overall coverage is robust.
