More than 30,000 deployed and forward-deployed sailors and Marines will get free calls this holiday season thanks to a program from the Navy Exchange. The sailors and Marines will receive either a free $10 prepaid card or virtual calling minutes using a virtual personal identification number (VPIN). Both the card and VPIN can be used aboard U.S. Navy ships or via shore-based telephone systems in the US and overseas. A list of U.S. Navy ships that will receive the free prepaid phone cards or VPINs can be found here.
