Analysts blamed the drop on a tougher credit control policy introduced by Vodafone into service providers which sold the group's airtime. Chris Gent, Vodafone's chief executive, said the reduction in customer contracts from 15 to 12 months had depressed the figures by some 35,000.
Orange, the newest network, topped the growth table for the second quarter in a row, though the increase of 86,000 to 980,000 was below the 109,000 recorded between January and March. Orange announced it had moved into the black, before deducting interest, taxes and depreciation costs, in April.
The biggest turnaround came from Cellnet, which added 74,000 net new customers between April and June. The first quarter had been disastrous, with an increase of just 12,000.
