texts wont go out

I need help I don't know about this stuff my texts will not go out. I may have deleted the android 2.3.6 system. Well one of 3. Does anyone have like an upgrade or reinstall or restore for this???

 

Everything on phone works except the texts don't go out. When you say rooting the phone is that like factory default? There is like 3 android systems in my settings under applications. One of them has 0 data. This is just a guess. I think there were only 2 androids in the running section. And there still is. If I have to root as you say. Can I save my apps and info ? Can anyone send directions. And Most of all THANK YOU for answering

 

Amarie82. It has a little red flag that pops up and says text not sent. I am recieveing texts just fine and everything else works fine. I may have accidentally deleted a piece of operating system. Not sure. But one of them in settings says 0 for data. I am wondering if I can upgrade if that would reinstall op sys. But if I root or default. I wiill lose everythning. I need this to talk to my little girrl. And text is what I use most Thank You for answeri ng

 

Thank you for help. Now after 3 day it works again. I found out some stuff that may help others. First if you do delete a systems apps data. As I thought I may have. The systems part keeps the applications need data that runs it I tried this on some others and while it will delete the data it keeps what it needs to run. This phone is kyocera milano. And I do like it esspecially key board. I am not young and i this is first technology I've ever had. Second I called boost mobile 3 times and they never gave me straight answer if there was worrk in area. If you hav@e problems insist on that. Thank you again Everyone for help and support. I would like to know more about rooting and if this will help me??
