Cell Phone Reception Hawaiian Beaches?

[ckg]

We are new to the area and are checking what cell providers work well in the Hawaiian Beaches area? We use Sprint now and while good in Hilo and Pahoa Town it is borderline about halfway down Kahakai so looking for maybe ATT or Verizon if they are better as our contract is almost up. I think I heard Verizon was better generally in the area but curious on current opinions.

Our priority in cell is usable for calling. All the data speed stuff is secondary.

Thx
