This year marks an interesting turning point for OnePlus. In December, it will hit the five year mark. The Oppo-backed company has managed to grow significantly in that relatively short window. Back in June, it noted that it had sold one million units of its latest smartphone in the first 22 days.

Continued growth will require some strategic partnerships. In the States, that means partnering with a carrier — after all, most smartphone users still purchase devices through those channels here. Fittingly, along today’s launch of the 6T, OnePlus is announcing its first U.S. carrier partner, T-Mobile.
