Email access via 2 step verification and an incorrect unused mobile number

[DC5]

I have been using sky email on my laptop for many years and now i cant log in as it requires a 2 step verification.  The mobile number that was used is now not in use

Do you see this option at the bottom of the "we are sending you a code" page:

"Use a different number" option at the bottom of the 2FA page ?

If you don't then you will have to call Sky about this as it might take a little while to get your number updated.
