Does it say ‘reading SIM’ when you go into the connectivity menu? When my service drops, that’s the message I see.Since trying to get my nano Google Fi SIM to work earlier this week, I've got no mobile service at all and I no longer have phone app access to the car. I put the AT&T SIM back in and it seems to recognize I inserted a SIM, but won't allow me to set it up manually and won't find a network in "auto" mode. I have WiFi setup, although I needed to connect it manually again, but the phone app and WattCat won't connect to the car any longer. If this goes on much longer, I think I will be making a service appointment. Maybe finally get my TCU 14.2 updated.
My trial period with the AT&T SIM has expired and I didn't renew it, but I would think it would recognize the SIM even if I didn't get service. It did auto setup my Google Fi nano SIM more than once even if the service was no better than 3G, but no longer sets up that SIM either.
I may have to make an appointment after all if this continues, but I’m not hopeful they’ll find the issue if it’s intermittent. I hate intermittent issues and I’m doubtful this kind of thing leaves error codes.
