when i'm texting I have to limit myself to 160 characters or less. When it goes over and I send, it never stops sending. It's on perpetual "sending" on my phone. And then it tries to resend later. This happened on my other Optimus as well. I know its able to send more than one text atta time, because I used to do it on my Ascend all the time. How do I fix it so I'm capable of sending long winded messages?
