OnStar has slotted the last piece into its Connected by OnStar 4G LTE service today by finally laying out its price plans for in-car data. The LTE data service will see a radio and WiFi access point installed in the 2015 Chevy Malibu and to some 30 other GM cars by year end. Both US and Canadian packages have been announced with tiers for monthly users, plus day and year passes for more flexible usage. Unfortunately, the curated app store we've heard about won't see the light of day in 2015. So, while it's great to have simplified data access and improved service with simultaneous data and voice, the delay may temper your enthusiasm.Current OnStar Safe & Sound or Directions & Connections customers in the U.S can grab a 200MB a month plan for just an additional $5 a month or spend up to $50 for 5GB. Plans also exist at other tiers with 1GB available for $15 and 3GB for $30. Note that non-suscribers will need to shell out an extra $5 per month for either of the two cheaper packages. 250MB Day passes are just $5 and 10GB buckets are $150 for subscribers and last a whole year. If you're already an AT&T customer, you can also opt to add your shiny new car to a mobile share plan for $10 per month. Canadians will pay $5 more a month for the two lower brackets and $10 for the two larger plus a whopping $50 for the 10GB yearly allowance. Finally, if you're still feeling unsure if this is really for you, don't fret as there's a 3 month free trial included with all LTE-enabled OnStar cars sold this year.
