If sales keeps up the pace, it could top the 1.5 million iPhone devices Sprint sold in its most recent quarter. T-Mobile's strong sales numbers are also impressive considering the iPhone 5 launched in the U.S. about seven months before arriving on T-Mobile.
As for the first quarter results, T-Mobile said it added 3,000 new customers at retail stores, the first time since 2009 that the wireless carrier was able to do have a positive net gain in what it calls "branded customers."
This year has been a time of big change for the carrier. Besides adding the iPhone to its lineup, T-Mobile also recently closed on its acquisition of MetroPCS, and in March, it stopped selling users service contracts. Instead, T-Mobile switched entirely to a prepaid plan.
“We ended the quarter with strong operational momentum, which is continuing into the second quarter, driven by the successful launch of our un-carrier 'Simple Choice' service plan and the introduction of the iPhone into our device lineup," T-Mobile Chief Executive John Legere said. "Things only get more exciting from here, having brought T-Mobile USA and MetroPCS together to create the wireless industry's value leader and premier challenger.”
However, the quarter was not perfect for T-Mobile. Revenue for the quarter was $4.68 billion, down by more than 7% compared to the same period last year. But T-Mobile's first quarter ended March 31, meaning it didn't include revenue from its new iPhone customers.
