The press release threatens that anyone who arrives without a working cellphone, charged, with service and coverage in the arrival area at the airport, will be arrested:
An airport representative will collect the two forms and begin verifying their information. First, they will call their mobile phone number to confirm it rings right in front of them. If it does not ring, the person may have listed inaccurate information and is asked to verify the number. If the person refuses to provide a phone number that can be answered on the spot, law enforcement is contacted and they are subject to citation and arrest.
We have no idea what the purported basis would be for arresting someone who isn’t carrying a cellphone, whose phone doesn’t have service in Hawaii (especially likely if they are arriving from another country), or whose cellphone battery has run down from watching videos or playing games in airplane mode during a trans-oceanic flight.
