ATT has a plan to turn your vehicle into a mobile hotspot. For $100 outright, or $0 with a 24 month service agreement, you can purchase the ZTE Mobley, a device that will provide WiFi to your phones and tablets as you drive. The uplink uses ATT's LTE data service. The device can be added to the Mobile Share Value plan for an additional access charge of $10 a month, or connected with a DataConnect plan with monthly charges of $20 for 1GB or $30 for 3GB.
The hotspot plugs into the OBDII port that 1996 and newer cars and trucks have under the dash. The hotspot is on when the car is running, and off when the car is shut off. If you change vehicles, it's simple to move the hotspot to the new car.

Sure, you can accomplish the same thing by tethering your laptop or tablet to your smart phone. ATT is counting on the plug and play simplicity of the hotspot to attract customers.
