Can O2 block unwanted calls to a mobile?

[warmbell]

Hi,

I have been receiving a lot of unwanted spam calls on my pay monthly phone, I wonder if O2 offer to block such calls.

Thanks,

Gerald

O2 can't/won't block specific numbers though they do offer a one time only free number change if the problem gets too much for you.

Some phones have a call block option built in or if on Android there are apps to download that will allow you to block specific calls or numbers.
