Sim card registration failure how to contact o2

[Anonymous]

My phone is saying "sim card registration failure". I want to contact o2 as it has credit on it (pay as you go), either o2 are blocking it for some reason so it wants unblocking or the sim card is faulty and i need a new one with the credit transfering. The o2 web site chat is coming up busy all the time try later. Is there any free way of contacting them? if the credit is lost and I have to pay again then o2 loses 3 customers one of which is quite a heavy user as mobile is her only phone but this level of fault reporting is unaceptable and orange will be given a try.

When was the last time you made a chargeable call? Maybe it has been deactivated if you haven't used it for a while. Try cleaning the sim and rebooting the phone.

There is an email link or chat link in my signature and bar going instore, these are the only free ways of contacting O2 on P&G.
