description Systems and methods of operating multimode 3G/4G communications devices in an overlapping 3G/4G coverage area (e.g., WiMAX or LTE/CDMA EvDO) include determining if a number associated with temporarily-disabled sectors of an available sector set of the multimode device while the device is operational with a 3G base station is at least equal to a threshold number. If the number is at least equal to the threshold number, a scan for a sector in the 4G network to handover the operation of the multimode device from the 3G base station associated with the 3G coverage to a 4G base station associated with the 4G coverage is initiated. A scan for a fixed period of time for a new available sector in the 3G network to be added in the available sector set may be initiated; and, if a new available sector is added to the sector set, it may be redetermined if the number associated with the temporarily-disabled sectors is at least equal to the threshold number, before initiating the scan for a sector in the 4G network.
