Mobile communication terminal and method for operating the same

A mobile communication terminal and a method for operating the same are disclosed. The mobile communication terminal can be connected to first and second communication networks. The first communication network may be a legacy network and the second communication network may be a Long Term Evolution (LTE) network. The mobile communication terminal is also capable of displaying a two-dimensional (2D) image and a three-dimensional (3D) image. The mobile communication terminal reproduces a 2D image, receives a display mode switch request signal from a user, determines whether 3D image reception is available according to an environment of a current connected mobile communication network, receives a 3D image from a server, if 3D image reception is available and a 2D image from the server if 3D image reception is not available, and displays the received 3D image or 2D image.
