5GUC

I would like to throw my complaint in here as well.  Ever since the 5GUC started showing up in my status bar, I cannot get reliable service (even with full bars in Manhattan, and a very clear view to the east).  People are getting my voicemail the majority of the time, and my phone sticks on "Calling..." without ever going anywhere, no ringing sound, etc.

Data has been very unreliable as well.

I am wondering if this has something to do with authorizing the sim card.  I regularly see an icon with an x over a sim card as it is disconnecting and reconnecting.  Restarting the phone or using the "Fix Connectivity" button temporarily resolves it, but it will act up again within minutes.
