I have the blackberry curve 9330 which I got yesterday and it has not been sending text messages to several people. Several people have received my texts though. When the people who are not getting texts send me texts, I get them. When trying to send them texts it shows no error message and appears to go through with the check mark but does not. I took my battery out and that worked for a while or at least with some people but now it appears to not be working again. I have a verizon phone and it has not worked for various people from verizon to iPhone, etc. However, some with iPhone and verizon have gotten the messages, so I don't know how it is determining which ones to send and which to not. How do I fix this?
