Text Messages Won't Send

[laxman12786]

I'm having a problem where I cannot send text messages, but can receieve them. I'm sure it's not a network issue because I'm receiving texts from other Sprint users. Basically, I used to occasionally get the "Message was not sent. Try again?" prompt - usually when I was receiving a text at the same time, but now it happens EVERY time.

It seems to be somewhat of a file size limit error maybe due to the fact that if I happen to have a message in the drafts folder and delete it then I can send one more text. However, I can receive a seemingly unlimited number of texts w/o encountering any sort of file size limit, so I'm not sure.

This happened once before a month or so ago, but it'd been over 6 months since I cleared messages so I figured maybe there was some hidden message count or file size limit. I chose "Clear Text Messages" from the menu, and my problems seemingly went away. However, it is now back a month later and I'm sure I don't have NEARLY the number of messages stored now as I did then - which would seem to indicate it's not a file size issue.

I also have plenty of memory space available. Is there something I'm missing? Taking the battery out does nothing, and I'm trying to avoid a hard reset. Sprint is pretty much useless.

Any ideas??? Anything to check? Registry keys to change? Files to delete?
