Wireless data plans are in vogue right now with carriers announcing new plans at a rapid clip only to improve upon them days later in response to the competition.

On Tuesday, the unlimited data offering spilled over into the automotive industry with Chevrolet becoming the first automaker to unlimited 4G LTE connectivity.

Available from March 3, those whose vehicles are equipped with an OnStar 4G LTE Wi-Fi hotspot will have access to an unlimited prepaid data plan priced at $20 per month. The offering, which will be available across Chevrolet’s entire retail lineup, is powered by AT&T.

Up to this point, monthly data through OnStar would set you back $10 for 1GB, $20 for 4GB and $40 for 10GB. OnStar also offers a 250MB day pass for $5 and a 20GB pass that can be used over the course of 12 months for $150.

Chevrolet notes that customers last year used nearly 200 percent more OnStar 4G LTE data in their vehicles compared to 2015. To put things into perspective, the automaker says owners and passengers streamed the equivalent of more than 17.5 million hours of video in 2016.

Curiously enough, Chevy’s press release didn’t say how much high-speed data its unlimited plan actually affords. If it’s anything like the wireless industry, you’d be foolish to think that unlimited actually means unlimited. If I had to guess, it probably adheres to AT&T's standard 4G threshold in which only the first 22GB of data is of the high-speed variety.
