BMW service bulletin · NHTSA ID 10206692 · Dec 2021 · also written SI B84 06 21, B840621
What it covers
A service bulletin tells BMW technicians how to diagnose or fix a known issue. It is not a recall: a repair under a bulletin is normally paid by the owner unless the car is still under warranty or a warranty extension applies.
The SIM card installed in the telematics control unit (ATM2) connects to different mobile providers' networks. However, due to a missing parameter, this does not work and can cause disruption in BMW ConnectedDrive services in areas with insufficient network coverage.
