The Harman Spark is a "Connected Car" device from AT&T that plugs into a vehicle's OBD-II diagnostic port, automatically creating a Wi-Fi hotspot for up to 8 devices when the ignition is turned on.
The Spark enables telematics for emergency assistance, fleet management, theft, tracking and more. This devices plug into the onboard diagnostic ports (OBD-II) of 1996 and newer model year vehicles that don't have built-in systems like OnStar.
Rate plans for the device start at $5 per month for plans without Wi-Fi, to a $30/month unlimited data plan. Plans including internet access are offered as both standalone or as an addition to eligible Unlimited and Mobile Share plans.
For shared data plans, currently, AT&T offers Mobile Share Flex data plans for aftermarket OBD-II devices. There is a $10 access fee per connected car device, in addition to the price of the plan.
Unlike AT&T's previous connected car device iteration, the Mobley, the Spark has specific terms of service and technical restrictions that limit use to a vehicle only - and AT&T reserves the right to terminate accounts for use outside of a vehicle. The Spark's Wi-Fi also shuts down after 30 minutes of not being in motion.
