We already knew that OnePlus was developing a 5G phone but now it has confirmed it will be bringing 5G handsets to Mobile World Congress (MWC) late this month.
In an email, OnePlus confirmed to Pocket-lint that attendees to the show will be able to "connect and communicate with our community over a 5G network".
We're not entirely sure what that involves, but there will also be a gaming demo over a 5G network, too: "attendees will also be able to experience the capabilities of 5G gaming on a OnePlus 5G prototype."
So that means we'll definitely see a OnePlus 5G phone there of some type - OnePlus confirmed it would be doing a 5G phone last autumn while OnePlus and Qualcomm announced in December that it would use Qualcomm's own Snapdragon 855 platform alongside the X50 modem.
At CES 2019, Qualcomm had a handful of prototype handsets on its booth including one from OnePlus' parent company Oppo, labelled as the Find X 5G.
The OnePlus 7 is not being announced at MWC - we're expecting that later in the Spring or early Summer. What's not clear is whether OnePlus' 5G phone will be a variant of the OnePlus 7 or a completely different device.
Qualcomm designed the X50 modem as an "add-on" chip separate to the main 855 platform. That means we'll see two versions of some phones this year, one with and one without the X50.
5G networks are set to launch in mid-to-late 2019 both in the UK and US.
