Thank you for contacting Nissan LEAF Customer Support. We appreciate hearing from you.
I am very sorry for the inconvenience. Nissan understands that AT&T has announced plans to terminate its 2G network coverage as of December 31, 2016. AT&T is a third party that Nissan does not control, and technology in this area is constantly evolving. Unfortunately, if your are a US resident and have a Canadian LEAF or vise versa you will not be able to partake in the use of CARWINGS. CARWINGS runs off of AT&T 3G towers. I do apologize for the inconvenience.
Please feel free to contact us again with any additional questions, through our website at www.nissanusa.com
or by phone at 877-664-2738. We are here to serve you from 8:00 a.m. to 12:00 a.m. (EST) Monday through Saturday.
