Unblocking mobile billing

[Jslev88]

Hello,
When setting up my phone I was asked if I wanted to block purchases to my mobile bill. Now I want to reinstate. Is there anyway to do this without contacting customer service? As I can’t get through on the phone, as this is a non urgent matter and I’m unable to use live chat.

@Jslev88 The only way is to speak to customer service. Numbers here: Guide: Coronavirus Community Help and Support 

O2 won't consider your call important, so use the Lost/Stolen or Fraud option if you have to, to get through. Otherwise you'll just be disconnected.

Alternatively, below is the advice from an O2 Guru on how to get through.
Call 202 from your mobile.
When it comes to the reason you are calling, stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
