An item-providing system supplies items to a user device for consumption at the user device via communication infrastructure. In one representative implementation, a user device includes a mode switching wireless communication module. The mode switching wireless communication module is adapted to receive a first paging signal via a first communication protocol when in a first mode of operation and adapted to receive a second paging signal via a second communication protocol when in a second mode of operation. The user device also includes a to-do list processing module. In response to receiving one of the first or second paging signal, the to-do list processing module sends a request to a remote network device. The request requests that one or more instructions be sent from the remote network device.
