Yes I Can make calls.  Zip is 37871.  It seems that all my calls go directly to voicemail except for one particular number.  When my sister calls it Rings!!  I am not kidding.  I've had numerous other people call and goes right to VM.  I've tried resetting the network settings...all the things that iPhone help said to do.   Im not seeing calls and   no voicemails are showing up. I tried leaving myself a message .. Didn't show up.
