Methods, systems, and computer programs for managing mobile device applications are described. In some aspects, a mobile device application is prevented from accessing resources of a wireless network. For example, a wireless network operator system can determine that one or more mobile device applications are disapproved for use in the wireless network. In some implementations, the wireless network operator denies the disapproved mobile device applications access to the wireless network resources. In some implementations, mobile devices disable access to the wireless network by the disapproved mobile device applications.
