The entire network is down currently so it's nothing you did.
To use that code, you first need to disable wifi calling in your MyO2, then after sending the code, you can turn it back on again.

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.

@Km1 There’s a nationwide outage so that’s why you have no connection

You will have to wait till the network is restored. There is a national outage at the moment
