Sorry I haven't updated this thread. Since I upgraded my phone (and the store used my same SIM Card from my 8100 in the new 8200), I went back and got a new SIM Card.
This seems to have solved the issue. No more dropped calls.
Generally, the phone is working pretty well. I have a problem that used to occasionally happen with my old 8100. I'm not sure if this ALWAYS happens, but if I receive a call while my phone is locked, I can answer it. But, if I then receive another call that I pick up on Call Waiting, I then can't seem to switch BACK to my original call -- I have to end the session and call the person back. And yes, I do know how to use the menu functions, etc. It will actually give me a message that says "operation failed." However, if my phone is unlocked (and I have made or received the FIRST call), then I have no problems with Call Waiting.
One more thing I like:
1. Toggling between Normal Ring and Vibrate (holding the # key) is MUCH faster than the 8100.
But, a new dislike:
1. When the phone is locked, I CAN'T toggle between Normal Ring and Vibrate (holding the # key). so, if I'm in a business meeting and suddenly remember my phone is on "loud," I have to first unlock the phone... then I can turn it to vibrate with the # key. With my 8100, I could still toggle between ring and vibrate with pressing the # key, whether or not the phone was locked.
