Just has a call from the Bristol SC. They are aware that there seems to be a problem with cars that have the Telefonica/Movistar eSIM, and are gathering evidence to try and determine what the issue is. I mentioned that others were having the same problem and was told that my car was the 25th that Bristol SC knew of with this problem.
I was asked to let all Model 3 owners know that Tesla would appreciate a service request from anyone that has this problem, with these key items of information:
1. Does the car refuse to wake up from the app when it's asleep?
2. Does the app work OK if the car is woken up by unlocking it?
3. Do you know if the car has the Telefonica/Movistar eSIM?
If anyone that hasn't yet submitted a service request, and that has this problem, could do so, then that would help Tesla try to resolve it.
I was also told that the fix isn't likely to be very quick, as at the moment Tesla don't know what's caused it, they are still gathering evidence (hence the request above). I got the impression that we're probably talking weeks (in Elon time) before the app will work again for those of us with this eSIM fitted. In theory, it should be possible to change the eSIM via an OTA update, I think, but I'm not sure if that's the case or not (I had thought that was one of the plus points for having an eSIM?).
