My IPhone 7 Plus is not letting me recive calls or call people

Whenever someone calls the calling screen comes up for a second but before I can hit the answer button it goes away. Then when I try and call them back it's goes to the calling screen but before it can even ring once it hangs up. This has happened with many different people so I know they arnt just hanging up or deneying my call. My carrier is AT&T.

IPhone 7 Plus is outdated

Take it to apple

Try factory resetting it

  • Will Do Not Disturb on iphone prevent no call ID calls coming through? - 1 I have a really pesky robot call quite often my question is, if i put Do no Disturb on… Will the no caller ID number come through? As in, will it show up on my phone that I have an incoming call. I don't want any alert status to the no call ID… No screen change, vibrate anything at all Hope there's enough information to give me a correct answer.
