What do you mean by call waiting?
Do you mean voicemail?
If so see here.

However many people have reported that some of the codes mentioned no longer work for some reason.
If you experience similar problems then you'll need to contact 48 support.

Ok, I understand.
Although this is for Three I tried it (*43# and Call) and it seems to enable it.
And #43# and Call to disable it.
Maybe you could try that?
