"sms blocked" error msg (T300)

Posted by CIMON3
I'm at a loss no one seems to know at tmobile or at ericcson. My phone randomly (it seems) when i try to send msgs will say "SMS Blocked Message Saved to Unsent" (all my settings appear to be correct and tmobile has me set up fine) but I can recieve and reply fine. ANYONE HEARD OF THIS?

I suggest you tell Sony Ericsson that you wish to have the software re-loaded and see if this fixes it. If not, talk to who ever you connected with and tell them you want a new SIM Card as you currently have a faulty one.
