I'm dropping 3-5 calls on average each day. Some of the calls I initiated and are with Land Lines. This never happened prior to the software upgrade, so I'm not sure what the issue is. Sounds like a completely different scenario than you experienced.
I have Sprint and my iPhone 5 practically never dropped calls--until I updated to iOS 7.1. It drops almost every call now, to the point that I can't use it. I need a fix, or a way back to the last operating system version.
