"We're not against having discussions with other carriers in looking toward the future with what's possible," Lau said, through an interpreter. "We're open and welcoming."

But there's a more practical reason for OnePlus to hold off a Verizon 5G partnership right now. Its first 5G phone, which will use Qualcomm's Snapdragon 855 chipset, won't support mmWave (millimeter wave), a band of the highest-speed 5G wireless spectrum that Verizon's 5G network will use. Instead, Lau said that the phone will operate on lower frequency sub-6 spectrum, which has a smaller internal antenna and is easier to deploy.
