Hi Pendz,
You need to phone 0800 953 9500 to get your box activated. You will need the box serial number, and your account and area number.
If you are having issues and the activation line isn't picking up then you could try speaking to New accounts and Set Up for them to complete the setup and activation. That would be options 1,1,1 and 4 if dialling 150 from a Virgin landline , or options 1,1,2 and 4 if dialling 0345 4541111 from any other phone.
The lines are open
Monday to Friday, 8am until 8pm
Saturday, 8am until 6pm
