Hi, hopefully some current owners can help me out. I'm trying to figure out how data usage works on the car. I know the car has its own LTE radio. I also have read that you can add the car to a phone plan. Volvo says that it comes with a "3 month (or 3GB, whichever comes first) complimentary data plan provided through AT&T" I also know you can tether your phone to the car. I'm trying to figure out which is used and how. I see that Volvo says that a "4-year subscription to Google Services included". Presumably this is separate from the 3 month AT&T plan referenced above. Does that mean that maps data doesn't require another data connection (Phone plan and/or tethered phone)? Does that mean that downloading things from the play store doesn't require another data connection (Phone plan and/or tethered phone)? How do apps that you install (Spotify, Tune-in, etc) access data? Thanks!
