Dial any number needed to exit the phone's network. For instance, some hotels require you to dial "9" before dialing an external phone number. Such information is usually posted on the phone. If not, ask the front desk person for assistance.
Dial the exit code for the country you are calling from (see "Resources" for a list.)
Dial "1" followed by the full 10-digit U.S. phone number (including the area code). For example, to call from Paris to Washington, D.C., dial: 00-1-202-555-1212.
