Under the agreement, all 2016 models with Audi connect will be delivered to customers with an AT&T SIM card providing connectivity to the AT&T wireless network for 4G LTE or 3G coverage.

Audi will also offer a Mobile Share data plan option to AT&T wireless customers who would like to add their vehicle to their existing smartphone or tablet data plan.

The latest deal follows the firms’ partnership on the first-ever in-vehicle 4G LTE data connection in North America in 2014.

“The convenience and added benefit of having Audi connect services in our vehicles, along with Wi-Fi access for up to eight devices, serves as a competitive advantage for our brand,” said Filip Brabec, Director, Product Management, Audi of America. "We have been and intend to remain innovators in this field through partnerships like this with AT&T.”

Audi has previously said it plans to deploy 4G LTE network connectivity across its model line-up as new or refreshed models come to the market.
