Help Messages not showing up

Hi there, just moved onto owning the S3 from a HTC One X and have loved it so far. Only issue I have is actually getting to be quite a pain. Every now and then my text notification LED will start to flash and I discover that a text from someone has only half got through to my phone. The notification light flashes but no messages appear on my phone.
The strange thing is that my phone says it has full signal. Any help would be greatly appreciated
Thanks

Have you reported this issue to Samsung? If yes, what did they say?
