What is this app? Why is it so big?

I recently noticed a different app topping my app list when arranged by size (15.46MB) that I don't know what it is. It is called com.android.providers.telephony

unless I'm mistaken, it's your phone itself. Basically the software that tells the phone how to call and who to call. I could be totally wrong on that though. I do know that it most likely needs to be there for the operation of your phone.

Nevermind, I figured it out. I was getting a large text thread going and after deleting it, the app is no longer large
