Can't call, text, or FaceTime certain contacts

[Runnersw1n]

Recently I have started to notice that some of my contacts don't receive my FaceTime calls. That person called me and it went through. As we were talking, I learned that they also aren't getting my texts. I noticed that the little "delivered" messages isn't showing up. I decided to try and call that person and it rang once, then went to voicemail. They didn't end the call. When I went back through my messages, I noticed that they weren't sending for another individual. I thought it might be a certain wireless company, but they each have different carriers. I tried deleting our message history and resetting my phone, but neither seem to work. I went from being able to talk to them no problems, to not at all. They can still call and text me, but I cannot call or text them. HELP!

Ok, its a long shot but this is what I was experiencing on my son's iPhone 6. I did all the troubleshooting I knew and contacted Apple and as a last ditch effort, before a factory reset, the had me check the date / time on the device. Sure enough my son changed it. He learns these "hacks" on YouTube to trick certain games that only let you play x amount of lives per hour etc.

I could not believe it. But it impacts FaceTime, iMessage, etc.

Settings > General > Data & Time > make sure you have set automatically toggled on.

If this is not it I would maybe backup your device and restore to factory (Settings > General > Reset > Erase All Content......). Try it before you restore from backup to see if your having the same issues / challenges. Let us know if either of these resolve the issue.
