SummaryThe 3G network in the US has been shut down. This means that only the 4G network will be available. In the 4G network, voice calls will be transferred via the Voice over LTE (VoLTE) function. For this purpose, the SIM card must perform an IMS registration in the mobile communication network. Due to a production error, the telematics control units were delivered without an IMS configuration. The Connected Drive voice services (Concierge Call, BMW Assistance, and emergency call voice) can no longer be used regionally in the US in vehicle with telematics control units ATM-1 and TCB-4G. Voice control of the vehicle and all other telephone (paired mobile devices) functions are not affected. Emergency call location data is unaffected.
