AT&T Radiotelephone Service Helps Keep In Touch On The High Seas
AT&T High Seas Radiotelephone Service is a two-way operator-handled service that provides voice communications between ships on the high seas (or aircraft) and land telephones or other mobile singlesideband radio stations. The communications link between ship and shore is via high-frequency (HF) single-sideband radio with coast station equipment provided and operated by AT&T, and ship equipment provided and operated by the customer or agent.
AT&T Radiotelephone Service provides passengers on cruise ships (and other ships and aircraft with SSB radio), via the ship's radio room, a way to keep in touch with friends, relatives and associates ashore.
With a ship-to-shore call, a passenger may pay for the call on board the ship, place the call collect, charge the call to a third number (i.e., residence, business, etc.) provided someone answers for verification billing, or preregister prior to sailing for billing to home, business or AT&T Card by dialing 1-800 SEA CALL (732-2255).
Cruise passengers are encouraged to utilize preregistration without cost or obligation. It is for their convenience. Cruise ships are using AT&T's Radiotelephone Service and thousands of commercial and private boats, including U.S. Navy vessels are registered for the service. The service is generally used when a ship is more than 30 miles offshore, where other forms of short-range radio transmission begin to fail. However, the service can be used even while docked.
AT&T provides free weather broadcasts through the service and gives special priority to calls from ships in distress, making fast connections to rescue authorities and holding the line until all is safe. For free literature about AT&T's High Seas Radiotelephone Service,
