(Telecompaper) AT&T reported higher profits for the second quarter, as lower costs helped offset falling sales in its legacy fixed and consumer mobile activities. Revenues fell 1.8 percent to USD 39.8 billion, while operating profit improved to USD 7.3 billion from USD 6.6 billion a year ago, thanks to reductions in operating costs. The adjusted operating margin, which excludes merger-related costs and other one-time items, rose by 150 basis points year-on-year to 21.6 percent.
