My parents are travelling to Naha for one week, and would like to get a sim card at the airport upon arrival. They would prefer a counter/shop to help them, as they are retirees, and need help with setting up the phone. A self-service kiosk will not be using for them, as they do not know which one to buy and how to setup.
1.) Please tell us which shop to go to in the arrival lobby of Naha Airport for data sim card.
2.) Any recommendations of type of card to purchase?
