​GM Just Added $50 To Your Cell Phone Bill

GM has been teasing LTE data connections on its cars for over two years. Now, it's official. In June, the Malibu will be the first car GM car with OnStar 4G LTE, granting traveling salesman high-speed data for between $5 and $50 a month.

The new LTE service will be provided by AT&T, allowing you to turn your car into a rolling WiFi hotspot so the kiddies can stream the latest Adventure Time on their tablets. But it ain't cheap.

For OnStar subscribers, 200 MB of data starts at $5 a month, with 1 GB offered for $15, 3 GB at $30, and 5 GB at $50. You can also buy it ala carte, with 250 MB for one day at $5, or cough up $150 for 10 gigs over the course of a year.

On the plus side, if you're an AT&T subscriber, you can add your car just like you add Aunt Sally. For $10, your car gets tacked onto your Mobile Share Plan, tapping into your monthly bucket of data.

The rest of the 2015 GM line-up, including Chevy, Buick, Cadillac, and GMC will get the service later this year, joining BMW and Audi, which already offer high-speed data to satiate their gilded children.
