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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for updating a prepaid balance","description":"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.
