The OnePlus 6T reportedly out-sold the 6 by 86% in US first-day sales
The 6T is essentially the OnePlus 6 with a new teardrop-style notch and an in-display fingerprint scanner in place of the typical rear-facing biometric hardware. Besides this, it is the first flagship from its parent company to be sold in partnership with T-Mobile in the United States. Under the terms of this agreement, US customers could buy the phone either outright or via a financing contract through the network.
The carrier also has exclusive rights to sell the 6T's Mirror Black 8GB/256GB variant in the country. This new business model has apparently resulted in a considerable uptick in sales for OnePlus. The XDA has reported that the 6T has outdone its predecessor by 86% in first-day sales. Therefore, it appears that the T-Mobile association has made the brand much more popular in the US already.
However, consumers thinking about getting their 6T through the carrier route should be aware that there are some differences between unlocked and T-Mobile-branded devices. The carrier-associated phones have a Google Feed built into the launcher, whereas variants bought direct from OnePlus do not. Buyers should also be aware that software updates may arrive more slowly to T-Mobile 6Ts, and that their bootloaders cannot be unlocked until they are paid for in full.
