Is there cell phone service on Maui and this tour?

Maui has cellular service throughout the majority of the island, Sprint and AT&T have decent coverage, and Verizon has an extensive cellular network. This tour takes the Road to Hana, which is a more remote area and, as a result, has more spotty coverage. 1. Road To Hana Maui Day Tour From Oahu 2. Small Group Road To Hana Tour 3. Road to Hana Tours
