No, it can only be provided by AT&T. But it doesn’t have to be connected to any other plan, such as your phone plan. They have a stand-alone car plan: for I think $20 you get unlimited data in your car.
This. Just got re-upped for $20 today actually.No, it’s $20 / month and it’s prepaid. Stop any time, no contract.
The $10 is if you DO have an AT&T phone, then you can add the car for $10 to your existing plan. For example if your phone has a 10GB plan, then you can pay an additional $10 / month to let your car use some of that 10GB.
