"Is there any way to turn the SMS feature off?"

So asks Tim Worstall on his blog:

So, all mobile phones have SMS or texting on them.

Is there any way to turn that feature off?

Specifically, a way to turn it off so that anyone who tries to text you knows that it didn’t go through? And that it won’t?

As much as it might wind me up, I can see that some people would really like this feature on their handset/mobile account.
