  • Why don't I receive alerts or a notification when I receive a text and I already checked my settings? I adjusted my setting and even put the ringer and notifications on and put the volume and ringer on and I receive no alert, no pop up, alert or notification when someone texts me. Why? This is the iPhone X! I went to the cell phone/ carrier store and they didn't help me. They said to go to the apple store or check the settings. I already adjusted the settings. So what do I do now?
  • Why do I receive text messages and missed calls on my old Iphone. How do I stop this? When someone calls me on my new phone, it shows up as "missed call from ___".It doesn't ring on my on my old phone, but after I answer the call on my new phone, it says missed call on the old phone, if that makes sense. I receive text messages from people on my old iphone as well. I use it as my iPod because it could drain the life out of my new phone, so I don't necessarily want to reset the entire phone. I have cellular data off and I'm with Verizon.

  • Verizon iPhone 5c can't make or receive calls? I recently got a verizon iPhone 5c as an upgrade. I've been using it for about a week and everything was running smoothly. Then all of a sudden I can't make calls or receive calls. I can text, browse, and use iMessage perfectly but when I try to call someone it makes the "beep beep beep beep" noise you hear in horror movies when a payphone doesn't work anymore, or when a landline is busy. It's just a repetitive dialtone.
