The OnePlus 6T was the first phone from OnePlus to launch on a U.S. carrier’s network, T-Mobile. That partnership has done exceedingly well for the company as it has helped boost the sales of the OnePlus 6T by 249 percent.

As per Pete Lau, OnePlus CEO, the first 30 day sales of the OnePlus 6T was up by 249 percent when compared to the OnePlus 6 in the United States. The OnePlus 6 in itself was extremely popular and sold 1 million units in just 22 days. The expanded availability of the OnePlus 6T in retail stores of T-Mobile is definitely going to help OnePlus’ brand image and the overall sales of the device. The attractive price tag of the device further acts as an icing on the cake.

To further strengthen its relationship with U.S. carriers, OnePlus will also be among the first OEMs to release a 5G phone in 2019. That should help the company to get the device on more carriers and network stores which should ultimately translate into higher sales.

In the interview with PCMag, Lau also addresses the lack of headphone jack on the OnePlus 6T. He says that while it was a painful decision, the company had to take this step as the screen size and battery kept getting bigger thereby limiting internal space. By ditching the headphone jack, OnePlus managed to include a bigger 3700mAh battery on the OnePlus 6T for improved battery life.

The company is also looking for security audit partners in a bid to improve its public perception with regards to security. Most users believe that since OnePlus devices are so cheap, they are not as secure as offerings from Samsung or Google. As for their Smart TV, Lau confirmed that its team is working on it, though there’s no concrete date for a product launch.
