In many major metropolitan areas, we offer The America's Choice Plan with OnStar.* You can link built-in OnStar Hands-Free Calling with a handheld Verizon Wireless digital phone in a single plan. Share the minutes between both lines, have the convenience of one bill from Verizon Wireless, and still get the safety and security of the OnStar service. Find out more.
