Your phone still locked in at&t network and you must unlock it before you can use your centennial sim card in that phone. To unlock pantech c520 network you will need a reliable pantech unlock code and you can obtained that code from at&t either third parties sites on internet.

Pantech C520 is a very temperamental phone and without the handset in front of me I can only give you a few things to try.

Pull out the SIM card and clean the contacts on both the card and phone. Lightly rub the contacts using a pencil eraser. Replace the Sim card and battery, try to make a phone call. If that did not work place the SIM card into an unlocked phone. Working in this phone then either your handset need to be reset (master) or is broken. Not working in the unlocked phone means your Sim card is bad and need to be replaced.

You can't unlock a phone for free sadly. Call Pantech, see if they will give you the code, if not - you might have to pay for it. best of luck, sorry for the problem!
