Now, notice that the word "prototype" is in there, as the company is not planning to announce this smartphone at MWC 2019, but will rather show its prototype, just to showcase 5G in action, basically.
Without knowing key details of the upcoming device, there will be some known features belonging to the 5G-ready handset, and these have not been teased by OnePlus as yet.
OnePlus has also emerged as one of the Top 5 Smartphone Brands in US in Q4 2018.
Qualcomm designed the X50 modem as an "add-on" chip separate to the main 855 platform.
Pete Lau, CEO and founder of OnePlus, said: The pursuit of speed has defined the OnePlus DNA since OnePlus was founded five years ago.
The smartphone is now available for general sales across all channels including OnePlus.in, Amazon.in and Reliance Digital, Croma outlets and all OnePlus exclusive offline stores.
There's no word yet on United Kingdom pricing, but as the OnePlus 6T starts at £499, we can expect the as-yet-unnamed handset to fetch around £599.
OnePlus are leaping ahead in the industry with their community driven phones and as they have been maturing as a company they have been producing nothing but winners.
It's interesting to note, however, that, despite its capacity to run demanding games with relative ease, OnePlus didn't mention that the prototype phone is able to download videos faster, play high-definition movies clearer, and allow for smooth streaming.
A report from CNET Spain, citing sources close to OnePlus, claims that the company's first 5G device will also be the first in an all-new lineup from the company that will co-exist alongside its current array of numerically-branded devices.
OnePlus has signaled multiple times in the past that it will be one of the first companies to launch a 5G smartphone in the market.
5G networks are set to launch in mid-to-late 2019 both in the United Kingdom and US. The company has only given a short indication about this device for the MWC visitors.
