Mobile operator O2 has upwardly revised its revenue guidance after revealing a 15 per cent rise in UK revenue for the last quarter.
For the 11 months ending December 2006 the firm, acquired by Spanish telecoms giant Telefonica for £17.7 billion in the new year, now expects returns of between 14 and 15 per cent.
In Germany and Ireland, O2's other countries of operation, revenues for the third quarter were up 6.1 per cent and 1.7 per cent respectively.
The operator's average revenue per user data, a key performance indicator for mobile phone companies, reveals a slight rise in Britain to £272, while the average fell slightly in Germany to €299 (£201) and €545 (£367) in Ireland.
Peter Erskine, chairman and chief executive of O2, today said: "O2 has continued to thrive as part of the Telefonica group and in the third quarter we have maintained our momentum in highly competitive markets, adding 812,000 mobile customers, taking the total mobile customer base to 34.4 million, 14 per cent higher than last year.
"In the UK we added 524,000 net new customers, driven by our customer focused propositions and ongoing strategy of treating both new and existing customers equally."
O2 also today revealed that in the year ending September 30th its customers sent 6.49 billion text messages, a rise of 26 per cent.
