The area code for Barbados is 246. Local calls from private phones are free; some hotels charge a small fee. For directory assistance, dial 411. Prepaid phone cards, which can be used throughout Barbados (and other Caribbean islands) to make local or international calls, are sold at shops, attractions, transportation centers, and other convenient outlets.

Your U.S. service provider may offer a reasonable short-term international talk, text, and data plan, but be sure to turn off the phone's "data roaming" feature when traveling internationally, as the application updates that continuously occur in the background whenever your phone is turned on are prohibitively expensive if you’re not in a Wi-Fi environment.
