If you have to call the Unites States while you are in the French West Indies, you have options in addition to pay telephones with either French coins or prepaid cards. This is a very helpful site for persons calling overseas. The MCI Travel Guide contains links to information on calling abroad from the U.S., calling the U.S. from abroad, and calling abroad from abroad. MCI's Travel Assist is available to holders of its Calling Card. No information is given for any of the French West Indies.
Sprint provides the least useful site.
Its Sprint Access Codes provides the toll- free numbers to dial from abroad, but you have to search that page for further information on products and services. And you will have to follow the link to Global One for additional information on international calls. If you or a family member are planning on spending a substantial amount of time abroad, check with each company's Web site for international call plans. VoiceNet appears to have the least expensive tolls, and it charges in increments of six seconds instead of rounding up to the next full minute. Access numbers and a printable list of access numbers are available online.
