(Telecompaper) T-Mobile USA has reported success with its new 'uncarrier' strategy, adding over 1 million new customers in the third quarter. The mobile operator added a net 1.023 million new customers in the three months, including 648,000 under its own postpaid brand, for a total of over 45 million at the end of September. Revenues increased by 7.4 percent quarter-over-quarter to USD 6.7 billion, primarily due to the inclusion of MetroPCS results for the full quarter and higher equipment revenues due to record smartphone sales. Service revenues increased 8.0 percent on the same basis to USD 5.1 billion, and smartphone sales surged to 5.6 million units thanks to the launch of the iPhone. Branded postpaid ARPU decreased by USD 1.40 compared to Q2 to USD 52.20, as the number of customers on the lower-price Value and Simple Choice plans rose to 61 percent from 50 percent in the previous quarter. Pro forma Adjusted EBITDA improved by 6.2 percent over the second quarter to USD 1.3 billion, reflecting lower promotional spend and cost controls. Cash capital expenditure reached USD 1.0 billion in the quarter, and T-Mobile maintained its full-year outlook for spending of USD 5.2-5.4 billion. It also still expects adjusted EBITDA of USD 5.2-5.4 billion for the full year. It will expand the MetroPCS brand to another 15 markets from November 21 and also continue to redeploy MetroPCS spectrum to reach 2x10 MHz for LTE in 40 of the top 50 markets by year-end.
