Hey guys. I've been using my 3GS for a while now and its been fine since I've brought it back from Melbourne.
Yesterday I changed my sim card from Hotlink to the new 3G Maxis which I presume is the newest one.
So now I can call and receive calls and receive sms, but I just can't send one.

I've updated to the latest carrier settings, on iOS 4.1 and I've also reset network settings. Also I have tried this method
(http://forum.lowyat.net/topic/811408).

Any other solution before I go back to Maxis? It's not jailbroken

Problem solved after going to Maxis. An hour of queuing, and 2 minutes to solve it. Fault lies with them for not activating something.
