Abstract: Methods for operating a communications-enabled application, controlling a secure profile via an operating system, and operating a cellular network are provided. Operating a communications-enable application includes detecting a need for data transmission when the mobile device has a communications status which is incompatible with the need and sending a request to activate a secure profile. Controlling the secure profile includes receiving a request from an application to have data session access via a secure profile and activating a data session utilising a secure profile. Operating the cellular network includes receiving a request to establish a cellular network data communications session from a mobile device including the communications-enabled application and establishing a data session with the mobile device using the secure profile. A mobile device and cellular network for performing the methods are also provided.
