Abstract
Methods and devices for improving performance on a wireless communication device having at least a first subscriber identity module (SIM) and a radio frequency (RF) resource may include detecting, on a modem stack associated with the first SIM, an active communication in a first network that supports high speed downlink packet access (HSDPA). During the active communication in the first network, the wireless communication device may detect a signal disruption period, and determine whether an operational downlink mode for the modem stack associated with the first SIM does not match a corresponding downlink mode represented in the first network. Upon determining that the operational downlink mode for the modem stack associated with the first SIM does not match the corresponding downlink mode represented in the first network, the wireless communication device may trigger an internal instruction to transition to a new downlink mode.
