A method and apparatus for downloading and uploading digital data using a dual-mode wireless transmit/receive unit (WTRU). When in a first mode, the WTRU communicates with a first network, such as a universal mobile telecommunication system (UMTS). While the WTRU is in the first mode, a user of the WTRU may request the transfer of data to or from the WTRU, (i.e., a download or an upload). The user of the WTRU may also specify whether the data transfer is to occur when the WTRU is in the first mode, or in a second mode when the WTRU is communicating with a second network, such as a wireless local area network (WLAN). The data transfer may occur on a real-time basis or at a later time. In an alternative embodiment, predetermined criteria may be established for implementing automatic WTRU mode selection when data is transferred.
