IPhone 5 texting isn't working?

Every time I try to open my messages it just goes to a blank texting page and then closes itself down. I have tried that thing where you hold down the home button and the lock button at the same time but that hasn't worked. Anyone have any advice on how to fix this?

Hold the off button down, shut it down, take the sim out and then put it back in and turn it back on.
Hope i helped.

Hold down on the power button (on the top) until the "slide to power off" comes ups. Power it off. After about 2 minutes hold i the power button until the apple comes up on the screen. Leave it until it comes back and your problem should be fixed.

  • Why isn't Wi-Fi working on my iPhone? 3G works (that's what I'm using now) but Safari or anything else that uses internet won't load when I use Wi-Fi. Why won't it work?
  • Why isn't my iphone texting other iphones through imessage? It's updated and so is the person I'm texting. I'm able to text some iphones but not other ones. Even iphones that are new text through the SMS thing. Why?
  • Why isn't my iPhone charger working? I have an iPhone and it was working fine but yesterday when I plugged it into my phone it would not charge. So I tried my brother's iPhone charger and it worked. I looked it up online and I think there's a problem with my USB cable and not the wall charger itself. What do I do?
  • Left side of my iphone 4 screen isn't working? Nothing on the left side can be pressed! I did a hard reset (pressing the home and off button) but it didn't work. Then i completely reset it, but there's no difference. I don't have an apple store where i live, how can i fix my phone? Btw, i can still do the *slide to unlock* which is odd, considering that that requires use of the screen's left side
