Hi,

 

I have a pay monthly contract and want to activate call barring whilst abroad.  However I don't know the 4 digit password and when I put in the standard 0000 or 1234 is says 'Call setting error' 'Network or SIm card error'.

 

Does this mean call barring was never initial activated by O2?

 

Thanks

Try 5555

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
