My iPhone won't let me send or view texts?

My iPhone 5 isn't letting me open messages anymore. As of the last few days, sending and receiving texts were slow, but now it's impossible! My signal is also low where it wasn't previously? How might I fix this?

Try resetting your phone? Sometimes that can help.

If that doesn't work, check your phone settings.

If all else fails, go to your phone provider and get it checked out.

Best of luck
