I don't know if you're having the same problem I had, but this sounds very familiar to me...
I had a similar problem last year - SIM not being recognized, real-time traffic flow not working - essentially, my car had no connection to the outside world.
I went back and forth with the dealer - software updates, and other "tweaks" - until the woman who sold me the car finally figured it out...
It wasn't the SIM card - it was the master unit (located in the overhead console) that connects the car to the outside world. Once that was replaced, everything worked as expected.
Good luck!!
