Number change

[Mark20]

Hi I’ve recently upgraded my phone and want to change my mobile phone number. I’ve tried to ring 202 who are fairly useless at the moment and just cut off your call. I can’t see any option on the My02 app to change it either

@Mark20 You'll have to persevere with customer service: Guide: Coronavirus Community Help and Support 

Alternative 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.

Because you're not buying anything, O2 doesn't consider your call important, so use the Upgrade, Lost/Stolen, or Fraud option to get through. Otherwise you'll just be disconnected.
