I'm sure that the SIM card could cause it, no question. However, after posting I upgraded the OS to 4.5etc.
Since my post I have not had ONE instance of SOS. Therefore, the SIM card is not the only issue that can cause this behavior.
One week, no SOS. I was usually getting the issue at least once per day. now ZERO.
