O2 Call Back message doo-dar

[DiscoKandy]

Hi,

I used to have the feature on my O2 contract phone whereby if your phone was turned off or out of signal it would send you a text message telling you who had tried to call whilst your phone was unobtainable. After accidently turning on my answer phone, I seem to have cancelled this service.

Now that I've turned the answer phone back off, how do I get this "call back message" service back ?

Thanks
