Incoming calls from one phone number does not come through. All others work.

If the number does not appear in your blocked list, there should be no other reason you cannot receive calls from this individual number. The only other thing I can think of is if you have ever used the block list with Verizon. The only other setting is Do Not Disturb, but if you are receiving other calls, then that would not be it. I know that you can set a Do Not Disturb individually on a text for an individual, but that should not affect phone calls. Check to see if you have a text conversation with this person and see if there is a crescent moon icon by them. You can see this and change the setting in the Details section of the text.

Have you done any troubleshooting? Try resetting the phone, it does not affect your data, hold the sleep/wake and home buttons together until you see the Apple logo and then release. The phone will reboot. The last thing I could think of for troubleshooting is to reset your network settings. While this does not affect your data, it will delete all saved Wi-Fi passwords. Go to Settings>General>Reset>Reset Network Settings. After that, I would not know of any reason a single caller could not be received.

If you have not blocked them, either on the phone or through Verizon, contact Verizon and open a case with them. I've seen it happen before with numerous carriers. It's a call routing problem on the network, either yours or the person who is trying to reach you. Might not hurt to have them contact their carrier and open a case as well.

Check to see if somehow this number was inadvertently blocked on your device. See if it is in the Blocked list. That would be the only reason you would not receive a call from only one number. Go to Settings>Phone>Blocked.

Thanks to Tom and Chris. I will contact Verizon on Monday to see if they can help me.

I'm having the same problem on my iPhone 6S (64 Gig, Verizon). I checked my blocked list, and the number isn't there. Like the original poster, all other numbers work fine, both for incoming and outgoing calls, and I can call the number in question just fine. Any other ideas as to what the problem could be? I also checked both the phone settings and the person's contact, but couldn't find anything that might be causing the problem.

Thanks in advance, and Merry Christmas!

I have had 2 incedences now where I have been told that they called and left messages on my cell phone. There has been no messge or missed call listed. This is quite distressing as I am waiting to hear back from potential employers.
