Cell Phones

Most major U.S. cell phone companies operate in Hawaii, and local cell phone calls are usually included in nationwide or domestic calling plans. Please check your provider as roaming charges may apply for some plans.

If you are traveling from another country, check with your cell phone provider regarding an international calling plan, service fees and whether your phone will be compatible. You may also rent a mobile phone after you arrive. 

As you explore the islands, please remember that due to the varied terrain, there are beaches, mountains and valleys where cell phone coverage is not available.
