General SIM card not recognized

http://androidforums.com – Today I got a replacement Droid 3, my old Droid 3 had camera issues. I switched over the SIM card, SD card, and battery from the old to the new phone, activated it, and everything works well except the new phone doesn't seem to be recognizing the SIM card. When I press the unlock button to get the phone to the unlock screen, it reads "Extended Network|No SIM Card." at the top of the screen. Also, when I go into location and security and press "set up SIM card lock" a message pops up that says "No SIM card found. Please insert a SIM card into the phone". Howev (General)
