Provided is an apparatus and method for searching for an accessible network in a multi-mode portable terminal in support of access to at least two different networks. The portable terminal includes a first communication module configured to communicate with a heterogeneous network, a second communication module configured to communicate with a mobile communication network, a Received Signal Strength Indicator (RSSI), and a controller. The RSSI determines if the portable terminal is in a service coverage area of the heterogeneous network. The controller operates the first communication module to demodulate received signals and determine if the received signals are of the heterogeneous network, when the RSSI determines that the portable terminal is in the service coverage area of the heterogeneous network.
