Pantech Matrix Says SIM Checking

I put a prepaid card in my Pantech Matrix and all it says is SIM Checking. How do I get it to load this SIM card?

    I have a pantech revue (I think). Every so often the words "sim checking" pop up. It used to be just when I would turn the phone on, but now it does it more frequently.

My pantech matrix cell phone says insert sim card


This problem arises sometimes because the mobile is unable to read the SIM. May be you should fold a small piece of paper in the same size of the SIM and keep it on top of the SIM and then insert the Battery. I think this will solve your problem.

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.
