new number

[Auriga]

I have a new phone and wish to register it with My O2 account. To do this you would send a verification code to my registered number which I no longer have so please advise how I register the new number.

Also the new number *********** receives calls but will not send out any - how to fix please.

[Mod edit: Please do not share personal details as your posts are visible to the public. Thanks!]

You'll need to talk to O2, Guide: How to find help & contact O2 has the Social Media links in it, most helpful those guys, once you get them to respond to your DM via X. Also this to help explain the porting process

Guide: Migration & porting into O2  @Auriga 

Good luck!

If, when you get into MyO2 register and alternate number in your contact details (I use my wife's Vodafone number.) Then when O2 wants to send you an OTP to log in it will give you a choice of numbers
