Whenever i turn on my Pantech Matrix, it says Invalid card, and shows a picture of a SIM card or something with an arrow pointing down.


Check to see if you SIM card is inserted correctly or if its loose. If that doesn't work you will unfortunately have to get a new SIM card. They run, I think, about 20 bucks.
