I have 3G, and all functions work. In the top right corner it shows the bars and #G but not the Verizon name.
When I go to settings-general-about then and then look at the "Network" it shows Not Available.
My wife has same phone and here it says Verizon as well as between the bars and 3G.
I have restarted, soft start, reset network settings and none have helped.
Battery life is greatly affected as it is always searching for the Verizon network.
settings-airplane mode (off)
I went looking at my iphone and that was the last thing to check.
if it still is not functioning bring it to a verizon wireless corporate store and have a tech look it over.
I was in Boston over the Weekend, May 3-5, 2013.
Received a phone call while in the plane just fine. Last phone call I received without resetting my phone daily.
The first time I called Verizon Customer Service the tech had me reset my entire phone. I asked why not just network and he said this would be better. So after 20 more minutes it actually solved the problem but I lost a lot of settings including ALL my ssid's that were stored. He said it was a once in a life time fluke.
The next day it happened again, calls looked like they were coming to my phone but I could not answer. I could not call back but I could text
Called again and a different tech had me just reset network. She also gave me her email addy in case I had this problem again.
FYI on day 2 my wife starting having the same issue.
very odd and very frustrating.
