User devices may search for cellular networks that provide the best available service, such as Long-Term Evolution (“LTE”) networks. If such a network is unavailable, the user device may connect to a different network, such as a Code Division Multiple Access 2000 1X network. When connected to the 1X network, the user device may not attempt to search for the LTE network unless the user device enters an idle mode, even if the LTE network becomes available while connected to the 1X network. Systems and/or methods, described herein, may “force” the user device into idle mode, while the user device is actively communicating via the 1X network, so that the user device may search for the LTE network. Forcing the user device into idle mode may include interrupting communications, which may include causing traffic, output by network applications of the user device, to not be transmitted from the user device.
