Starting later this year, AT&T will allow customers to add selected connected cars to their existing Mobile Share Value plans for as low as an additional $10 per month. Essentially, the cost for connecting a GM car will be the same as a tablet, $10 a month when added to a Mobile Share Value plan.
OnStar will usher in a new generation of connected vehicles next month, starting with the 2015 Chevrolet Malibu and followed by more than 30 other Chevrolet, Buick, GMC and Cadillac vehicles by the end of the year.
