OnePlus to release 5G enabled handset early next year with new design and branding
6

Back in June, OnePlus CEO Pete Lau told PC Mag that the company was already talking with U.S. carriers about releasing a 5G enabled phone in 2019. At the time, it appeared that the OnePlus 7 could be that device. However, the latest news out of OnePlus is that its first handset to support 5G will kick off a whole new line of phones for the company. In other words, the OnePlus 7 will not be the manufacturer's first 5G model.
Since OnePlus has spilled the beans about its first 5G phone, stating that it will be unveiled at the beginning of 2019, we could see it introduced at the 2019 Mobile World Congress (MWC) trade fair to be held in Barcelona from February 25th through February 28th.
