Capital improvements have enabled American Samoa to achieve an infrastructure that is enviable among most other islands in the Pacific. In addition to a well-established international airport and one of the Pacificâ€™s only natural deep-water harbors, Pago Pago has an excellent cruise ship port, container docks and other maritime facilities, as well as excellent roads, extremely reliable power, water and waste treatment systems. The American Samoa Power Authority (ASPA) has achieved an impressive record for quality and reliability. Even through droughts and hurricanes, ASPA has maintained service without interruption. Telecommunications within the island itself and off-island are robust. Three ISPs offer high-bandwidth internet service and two telecommunications companies now offer cellular phone service. American Samoa recently joined the North American Numbering Plan, which means that dialing American Samoa from the continental U.S. is no longer an international call.
