Systems and methods for permitting a user to select applications for trial on the mobile handset for network services and for applications installed on the handset. An example method shows trial and expiration messages to the user and automates the installation and/or deletion of the trial software according to the user's choice and the handset vendor's preference. The trial software is launched, and the trial commenced, based on an autonomous trigger, such as an incoming call or activation of the handset, rather than requiring the user to manually launch the trial application. |
