Abstract: Disclosed is a method of a mobile communication device, a device and a method of a server for updating the prepaid balance during the active mode of the mobile communication device. The method of the device includes storing in memory a stored prepaid balance prior to initiating a wireless communication via a service provider, initiating an active mode wireless communication and transmitting, during the active mode wireless communication, at least one balance query to the service provider. The method further provides receiving, during the active mode wireless communication, a response to the balance query, determining if the response to the balance query is valid and processing the response to the balance query to obtain a new prepaid balance if the response to the balance query is valid.

Abstract: A wireless communication device includes wireless communication circuitry that enables the wireless communication unit to communicate through at least a first wireless communication service and a second wireless communication service, and includes a subscriber identity information memory that stores at least a first subscriber identity information and a different second subscriber identity information. A user input is received and is used to select one of at least a first send user selectable input and a second send user selectable input. The wireless communication circuitry registers with the selected one of the first wireless communication service and the second wireless communication service. The wireless communication circuitry registers by employing a subscriber identity information corresponding to the selected one of the first wireless communication service and the second wireless communication service.

Abstract: A wireless communication device and method is provided for managing the call routing for multiple services each respectively associated with a corresponding one of multiple sets of stored subscriber identity information. The wireless communication device includes wireless communication circuitry, that enables the wireless communication unit to communicate through at least a first wireless communication service and a second wireless communication service and a subscriber identity information memory that stores at least a first subscriber identity information associated with the first wireless communication service and a different second subscriber identity information associated with the second wireless communication service. An indication is received regarding which of a selected one of the first wireless communication service and the second wireless communication service the wireless communication device is to employ.
