Alltel’s the number 5 US carrier reported its 2Q numbers. Its strong wireless growth was responsible for higher quarterly profit as the operator added 146,000 new new wireless subscribers in the second quarter and posted lower churn. The regional operator’s churn measured 1.47 percent. Average revenue per wireless customer (ARPU) was $52.54, a 4 percent increase, while data revenue per customer was $3.26, a 61 percent increase. Alltel said data ARPU represented 6 percent of total ARPU. Alltel spun off its landline phone unit two weeks ago so it could focus on the wireless business.
