I have just joined Virgin for my TV, Internet and phone, and it seems they need to send me an 02 sim card to keep the monthly price low anyone else had this.
Had exactly the same offer fruitsalad. To get the best deal they would send me a SIM card. Accepted the offer, received the SIM card (which i have never used) . Now receive an email statement every month for my TV, internet & land line phone ( which i rarely use ) and receive a separate email statement for the SIM which is £0.00. At the end of the day if you choose not to use the SIM it will not cost you any extra, that has been my experience at least.
Hope this helps.
Thanks guys, no I have no intention of using the sim, I have my mobile with Virgin, and yet its Virgin wanting me to use the 02 sim :) seems a bit daft.
