Old number

[turbomicra]

Hello  there.

I was a member of 02 a long time ago, I lost the simcard many years ago. The problem is that this number was registered to an email account I registered with in 2010. Which coinsidently I don't also remember. I saved myself as a contact on the old blackberry at the time as I'd always forget the number.

The number is not currently in use and is dead -

How can i retrieve this number and put it back in use for the sake of my email?

You need to contact O2.
All numbers are in this guide Guide: Coronavirus Community Help and Support 
Or 202 from your O2 mobile.
Advice from an O2 Guru to get through:
When you call 202, you will be asked for 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.
You can also try saying "Upgrade" or "Fraud" to be connected to an advisor.
