Why iphone 5s drops long calls on f?

On full signal bars?
i'm seeing thickness of my sim has tiny gap too

Dropped calls aren't the phone's problem. It's your carrier or the person calling you. Is it just with the same person? In the same spot? There are dead spots or possibly tower maintenance issues in your area. Best luck. For the sim tray, check with the Applestore for Genius Bar inspection. You have a free one year warranty on defects. Best luck.

I would assume that the company you have is Sprint.

  • When will the iPhone 5s and 5c have price drops? I'm looking to get a contracted iPhone, and I would really prefer the iPhone 5s, but the $199 price is a bit high. When do you think they will have price drops? Do you think it would be worth it now to get the iPhone 5c 16gb? I'm in no rush to get the iPhone, but I don't want to wait till Christmas or any time around there.
  • What should i do? My iPhone 6s plus drops on the floor? Today my iPhone 6s plus drops on the floor. Luckily it was inside a flip case of iPhone, my screen is safe but the upper part of the body got some scratches how to remove that? I'm scared is it possible to remove scratches on the body of an iPhone?
  • My IPhone drops service randomly? I backed up my iPhone 4S and it went back to settings and contacts from a year ago. Anyways I had to of course delete and re-add apps and contacts but now my cell service (I have sprint) will randomly drop for no reason. (Note: I just backed up my phone about 10 mins ago) should I be worried or will it fix itself?
  • My iPhone battery drops rapidly? My iPhone 4 battery drops so fast, even when I'm not on the phone it will drop, I haven't got blue tooth on what should I do?
