Change my phone number

[Fish]

Can anyone advise me how I can change my phone number

You need to contact O2 @Fish  Guide: How to find help & contact O2

Call customer service. They will change the number without the need for a new sim card

You should be able to do it in the app which is the best option

Otherwise you need to call

Everything is taking longer due to the lockdown. Call centres and social distancing means limited staff to handle all the queries. Patience needed I'm afraid.
