you probably (possibly) added a signature to auto-pop on your messages.  this makes the message an Enhanced message, which can't be sent inter-carrier.  anything over 160 characters, or with cutesy smiley faces and stuff added, also becomes an enhanced message.  Simply remove the signature and you will be good-to-go
