The metrics firm says that Verizon is on top in the U.S. with 37.9% of smartphone sales in the same three month period, a gain of 6.9 percent points. AT&T was second with a 21.7% slice of the U.S. smartphone pie in the three month period, followed by the 14.6% of sales belonging to Sprint. When T-Mobile first started selling the iPhone in April, most of the sales came from featurephone owners moving to their first smartphone. In August, 56% of T-Mobile's iPhone buyers were coming over from another smartphone, 38.5% of them switching from Android.
During the three month period ending in August, the top selling device at T-Mobile was the Apple iPhone. The latter made up 17.1% of T-Mobile's smartphone sales in the period. Despite that, the majority of smartphones sold at T-Mobile during June, July and August were Android powered models. The Samsung Galaxy series and the HTC One benefited from discounts. In August, the Samsung models and the HTC flagship were offered for 'zero down' which helped improve sales.
