I've been having an odd error when trying to call certain contacts. When I press the screen to call them, after a second or so the screen goes black and it says "CDMA: Retry Order" on the bottom of the screen. In the middle of the screen a popup comes up and says "Drag Right to Answer and Hold Active call"....but there's nothing to drag right. There's a dismiss button to touch, and I do, and that's it. No call. This only happens with some, not all, contacts. Seems like it started a few days ago, but maybe it's been longer and I havent noticed because I havent had to call these contacts. I cannot make calls to these people. Any idea what this is? I know these are working numbers, I've called them on my land line. Also, when I make ANY call with my phone, during that second or two before the call goes through there's a message at the top of the screen that says "No SIM card found. Please the phone". That's the exact wording...but then the call would go through anyway. Or, on certain contacts, I get the black popup I described above. What is all this?
