Call Barring

Can someone tell me how I can stop someone from calling my number? How do I use call barring?

As far as I am aware the iPhone does not support call barring but, then I may not have found it

It doesn't... most phones don't support incoming call barring on a per-number basis.

If you're getting numerous nuisance calls from a number you have asked NOT to call you however then this is harassment and you should speak to O2 about it who will be able to block the number from calling you

Need to ring o2 and ask them to put on call barring. The default password when enabled us 0000. Please note that if u have a call divert setup it will not work so basically u need to turnoff visual voice mail via 1760 before useing call barring. There are also only certain codes that can be used e.g bar all incoming, bar all outgoing etc..

Pwnage your iPhone, then you can install iBlacklist which will stop Phone calls and texts from any number you want

Pwnage

I had this problem on a previous phone, don't answer the call save the number in contacts call it " banned number" so you don't answer it automatically or you could divert it.
