My iPhone 4s was working perfectly, no problems. Then I upgraded to iOS7. Since then it's been a nightmare.
If I am not connected to a WiFi network (even thought he 3G symbol is on my screen) I cannot use apps, cannot access my email nor can I browse with Safari. I just get "not connected to the internet" messages, even though I clearly am on three 3G.
After reading forums I have tried the following:
--Toggling the Settings > Cellular Data on and off
--Toggling Airplane Mode on and off
--Resetting Network Settings
--Full Factory restore of phone.
--*228 Programming Update
--Enabling/Disabling Data & Voice Roaming
Alas, nothing has worked. And I know it's a Verizon 3G connectivity issue, because when I am on WiFi, everything works fine.
