Bulgaria’s largest wireless operator M-Tel, a subsidiary of Telekom Austria, has reported an 11.7% increase in revenue for the first quarter of 2007, compared to the same period of last year. M-Tel recorded sales of EUR141.8 million in the three months ended 31 March, compared to the EUR126.9 million in the same three months of last year. Its operating profit in the first quarter was EUR45.5 million, a 4,6% increase. Average monthly revenue per user fell to EUR9.9 in 1Q, from EUR10.7 in the same period of last year, due to price cuts, which were offset by an increase in voice traffic. M-Tel added 180,000 new subscribers during the period, to end the period with close to 4.45 million users, of which 1.66 million were post-paid.
