Implementation of mobile device communications (MCD) management is provided. A method includes intercepting an input command received on an MCD, the command intercepted in response to detecting a presence of a fixed communications device (FCD), which is embedded in a vehicle within range of the MCD. The method also includes acquiring biometric data from a user of the MCD. The method includes determining an activity status of the vehicle. If the activity status reflects the vehicle is active, the method includes acquiring biometric data for an operator of the vehicle via a biometric scanner of the vehicle and comparing the biometric data from the vehicle with the biometric data for the user of the MCD. If the biometric data from the vehicle matches the biometric data from the MCD, the method includes retrieving an account record for the user and implementing an action specified in the account record. If the activity status reflects the vehicle is inactive, the method includes executing the command.
