My notifications don't work? IPhone 5s?

I just bought my iPhone 5s today at sprint. And I realize that my push notifications aren't working including kik & instagram. All notifications Are on but they're not popping up?

  • Why don't twitter notifications work on my iPhone? No twitter app's push notifications work on my iPhone 5. I've tried the regular twitter app, echofon and tweetbot. All my notification options have been on in the settings of the iPhone and in each app. I've used each app singly, deleting the previous one every time I tried a new app. I've restarted the phone, reinstalled the twitter apps but nothing has worked. Been driving me crazy! My other push notifications work from other other apps except twitter.
  • Why don't I get notifications when I get a missed call on iPhone? Whenever someone calls me or facetimes me and I don't see it so it goes to missed call. But I'll go on my phone then and I won't get any notifications on the lock screen that I got a missed call. And there's no notification on the FaceTime app or phone app but in settings it says notifications are on. This happened on my old phone, then I got a new one and it was working for a little bit now I don't get notifications again. What can I do?
