I’ve been carrying this complaint a lot lately, and it’s resulted in me blank a lot of phone calls (some of them flattering important).  While I’m at work, my iPhone will inform 3G and full bars, though the phone will not essentially be connected.  If I try to have a call, all I get is overpower on the line.  If someone calls me, it goes true to voicemail.

 

This has been function to me for the past half year or so, and it’s tough to lane down any signs of the complaint since the phone reports a great connection.  What can I do?  Is this a usual problem?
