To make an international call, first dial "+" on the keypad (the U.S. exit code), followed by the country code and the phone number. For example, to call a phone number in the United Kingdom, enter "+44" and the local phone number on the keypad. To add "+," please firmly press "0" until "+" is added automatically at the top of the keypad screen.
*Please note that international calling may not work in certain countries due to carrier restrictions or costs.
