Verizon, the second-largest US telecom firm, reported strong second-quarter profits on Monday thanks to its growing mobile phone division, according to dpa. Net profits rose nearly 12 per cent to 1.9 billion dollars, or 66 cents per share, despite a decline in traditional land-line phone service, the company said in New York. Revenue rose 4 per cent to 24.1 billion dollars in the April-to- June period. Verizon gained 1.5 million new mobile phone customers in the quarter, up 11 per cent to 68.7 million total users. Market leader AT&T has 73 million mobile customers.
