Old VM data only contract now on O2

[abtrooper66]

I  have a VM data-only sim used in a mobile broadband dongle issued by VM which was moved across to O2 this year as part of the VM -->02 change. However, I can't change any settings on the account as the O2 online system wants to send a verification code to the mobile number associated with the SIM card. As I don't have a spare mobile to use to check this, how else can I now validate the account correctly with O2

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 using the links below, they should be able to help you with this

or give them a call on 202  or 0344 809 0202
