The Road to Hana on Maui has 4G coverage for roughly the first half of the route. Signal becomes patchy from Keanae onward with gaps in deeper jungle sections. Download an offline map of the Hana Highway before departing Lahaina or Paia. Signal returns as you reach Hana town.
Volcano national parks have limited coverage
Volcanoes National Park on the Big Island has reduced signal near the caldera. The visitor centre area has limited 4G. Haleakala National Park on Maui has very limited signal at the summit crater. Download the NPS app and park maps before arriving at either park.
Island-hopping between inter-island flights is straightforward
