VISUAL MOBILE PHONE. 

Sender Sim. 

When you will do phone of other person. then video camera will catch your face light in the shape of electron. and will send with sound through the Sender sim. and other side your friend will receive your video message and sound.

IT IS POSSIBLE. 

Because it is like television broadcast. or, you are seeing a any life show. and which person is in the television program. that they cannot see you. because the camera is on the front of his face. But if a camera is front of your face, and camera doing telecast your face film. then other side, they can also see you in own television. from this reason two sims are doing use into the visual mobile phone.
