Under the "My password & security settings" section under "My profile summary" there is an option to enter a new 4 digit PIN. What is this for?
In the FAQ section the only information I can find is this:
"Your O2 eService PIN (Personal Identification Number) gives you access to restricted areas of your O2 dashboard. It also activates extra security when you make changes to sensitive information for example your payment details."
I cannot see any restricted areas.. Or am I missing something?
