Can the other party see if the message is rejected?

No, others won't see that what the sender saw was normal transmission, but it didn't actually appear on your mobile phone because the message was intercepted by your mobile phone when it arrived from the base station. As long as the other party wants to send this message from the base station, it will be charged whether you are connected or not.
