Cable segment products. The decline in prepay customers reflects increased competition in the prepay
market and our strategy not to focus on the lower value end of the prepay market.

(1) Mobile customer information is for active customers. Prepay customers are defined as active customers if they have made
an outbound call or text in the preceding 90 days. Contract customers are defined as active customers if they have entered
into a contract with Virgin Mobile for a minimum 30-day period and have not been disconnected.
(2) Data cleanse activity with respect to the three months ended September 30, 2008 resulted in an increase in contract and
prepay mobile customer numbers as disclosed above. Data cleanse activity with respect to the three months ended
March 31, 2008 resulted in a decrease in prepay mobile customers as disclosed above. Previously this data cleanse was
shown within net prepay mobile customer additions (disconnects).
(3) Mobile monthly average revenue per user, or Mobile ARPU, is calculated on service revenue for the period, divided by the
average number of active customers (contract and prepay) for the period, divided by three. For the purpose of calculating
Mobile ARPU, we have spread the data cleanse evenly over the three months of the quarter in which the data cleanse has
been reported. This has the effect of revising the ARPU previously reported for the three months ended March 31, 2008
from £10.04 to £10.06 and the average number of customers previously reported from 4,465,200 to 4,457,800.
