Did Tesla switch off the AT&T network at some point in the US? I noticed I got network connection at grandma's house and confirmed I still don't get AT&T at her house on Christmas day. Last night at a friends new house I noticed the car showed no bars and my AT&T phone was solid. Someone else had the same thing on their phone maybe Verison but I can't remember for sure. Did they announce a carrier switch and I didn't notice or just do it without telling anyone?
