AT&T's March quarter results
included 4.8 million iPhone activations, data shows. The device represented 80 percent of the carrier's 6 million overall smartphone sales for the quarter. The figure compares favorably against the 4.7 million iPhones AT&T sold in the iPhone 5's launch period, but represents a significant if expected drop from the record 8 million sold during the December quarter.
Apple sold roughly 37.4 million iPhones in total during the March quarter. AT&T was once crucial to the device's success as its original carrier, but has since become just one of several iPhone providers in the US. The company has in fact tried to decrease its reliance on the iPhone, but has struggled to give attention to its other offerings, which are typically available at carriers like Verizon and T-Mobile as well.
