Consequently, AT&T’s 4.3 million iPhone activations likely
corresponds to approximately 75% of its total smartphone sales of
5.5 million units for the quarter.
Even more impressively, the continued trend toward smartphone
adoption means that the iPhone is representing a growing
proportion of total phone sales (smartphone and non-smartphone) at
AT&T. The carrier notes that smartphones represented more than 78%
of its total phone sales to postpaid customers, meaning that the
iPhone accounted for roughly 60% of AT&T’s total phone sales to
those customers during the quarter.
