Iphone 6 is stuck on the sending bar?

It's been three days since I send imessages and regular messages and it sends the message to the person except that they get the messages and the message bar is stuck there and then I exit the app and I go back and the messages aren't there anymore and its really getting on my nerves. I already did network reset and phone reset is my phone broken?

Its a network issue contact your carrier they will help, maybe there's a network update that you didn't install.

  • What is this iphone 4 status bar icon? This icon is a red horn with marks coming out of it simulating sound I suppose. I flip the silent/loud switch on and off and it doesn't make a difference. And a bonus, this icon is a phone, just a phone like one on a flip phone answer button. Please assist!
  • Unlock scroll bar on broken iPhone? Details below? There was rumors going around that if you crack the screen on your iPhone / iPod that the scroll bar to unlock the phone will eventually stop working, is this true? And approximately how long till that happens?
  • Volume bar on my iPhone 4 has disappeared? My volume bar has disappeared on my iPhone 4 when I play music through the speakers. I can't hear the typing of my keyboard either, but when I go into voice memos I can listen to them. After that I go into my music library and play music and the volume bar is there for about 5 second and disappears again. I have tried rebooting it and it's done nothing. The sound will just come and go. What the hell is wrong with my iPhone? Please and thank you. P.s it isn't jail broken either.
  • Stuck iPhone 4 lock button! Stuck/Stripped screws Okay so, I've had this stupid panda case on my phone and it jammed my lock button. It still works if you push super hard from the side, but no clicking sound. I saw how to fix it by opening my phone up but the screws won't come out no matter what! I tried a screwdriver alone, with duct tape, rubber band, double sided tape, everything! I don't have a warranty on my phone, and I'm looking for a super inexpensive (>$5) way to fix it, any ideas?
