O signal the phone does not get eny signal at all

The most common is that the cable that activates the camera is touching ground and this activates the camera and has nothing connected as black screen looks

is the sim card in the phone, a working sim card?

Hello,
If you have pulled the sim card out and verified by the diagram on the phone that you put it in properly, you may have a "burnt" sim chip, unless you have tried it in another phone with success. Burnt chips can happen for a number of reasons, some of which could be physical damage. You will need to go to a cell phone kiosk or store and purchase and activate a new one. They usually cost about $25. They would be able to tell you if something was wrong with the sim as well as they should have a sim reader on hand.

Your monitor should have a light on it that indicates if it has signal, if the light stays yellow(or blinks) as the computer boots it is not getting the signal from the pc. Check the VGA cable on the back of your computer, it a big blue connecter, it has to be unscrewed and and disconnect it to verify that none of the pins are bent, plug it back in snugly and see what happens.
