OnStar and Verizon Wireless Nationwide Plan with OnStar Program

OnStar and Verizon Wireless have discontinued the shared minute program for new enrollments.

Launched in June 2004, this program offered OnStar customers with select OnStar-enabled vehicles the option of adding their vehicle to their Verizon Wireless account and share Verizon Wireless account minutes.

Effective July 13, 2009, OnStar and Verizon Wireless stopped accepting any new customers on this program.

This decision does not affect those OnStar customers who already are enrolled in the Verizon Wireless shared minute program. While the shared minute program is being discontinued, OnStar customers can still enjoy the benefits of OnStar's voice-activated Hands-Free Calling by purchasing minutes from OnStar.
