First, restart your phone by holding the power button for 10 seconds. Make sure free calling apps like Viber, Tango or Skype isn't your default calling app or simply uninstall these free calling apps.
You should also check your call settings. Open the phone app -> tap on Menu -> tap on Call settings - > then scroll to the bottom and choose ""Use Internet Calling"" under Internet Call Settings. Make sure that ""Only Internet Calls"" is selected. I hope this will help you."
"I found the problem with my phone. I can get data, internet, text, but no voice phone. It turned out to be the radio antenna for phones calls. The grey wire on the right side was getting pinched when I screwed the back on. I also lifted the usb flex circuit board slightly, from the right. Cleaned the contact between the board and the antenna contact on the frame and pressed it back. That fixed it. So, check your grey wire connections or try replacing the wire.
Phone radio has a different antenna than wifi, 4g, Bluetooth. Etc."
I was having problems receiving and making phone calls. No calls were coming in and I couldn't make any calls. The dialer would timeout and no calls would ever go through. After looking through the threads on this I noticed many people had the same issue mostly with Samsung phones. So I thought it was my phone as I have a Samsung Galaxy 6. I also happen to use my old iPhone 4 as an iPod in the car or with earbuds and I noticed that lately it was showing up with missed calls. After reading the threads with no ideas given on how to fix the no call issue I decided to try test. I have always left me iPhone 4 in my car right outside the garage and back door of my house so after retrieving the iPhone from the car I turned it off and restarted my Samsung Galaxy 6. After doing this I was able to make and receive calls again! Hallelujah!! This is happened to me with a Galaxy 4 and the Galaxy 5 and I could never find the fix. It would just start working later on and I never knew how or why it started working again. So to recap if your phone will not make or receive calls check and make sure you do not have another Verizon phone somewhere that you used to use that is turned on. I cannot be sure but I think it's just this iPhone 4 that I have since it doesn't have a SIM card that has been giving me problems. I hope this help someone as I found this extremely frustrating and had it happen to me on several different phones. I would hate to think that someone would go out and buy brand new phones, waste their time at a Verizon store, or anything else when my problem was very simple to fix.
