A two-in-one connector includes an insulating housing, a plurality of first and second terminals, and a shielding shell. The insulating housing has a first base body and a second base body. Each first terminal has a first soldering portion projecting under the first base body to be mounted on a printed circuit board, and a first contact portion projecting beyond a top of the first base body. Each second terminal has a second soldering portion projecting under the second base body to be mounted on the printed circuit board, and a second contact portion projecting beyond a front of the second base body. The shielding shell is mounted on the first base body to define an insertion space therebetween for receiving a SIM card therein to contact with the first contact portions. A battery can be mounted on the shielding shell to contact with the second contact portions.
