At the company's "5G Day" event in San Diego yesterday, Qualcomm announced that it had secured 18 OEM partners to build 5G devices using its new X50 5G modem in 2019. Notable among them are handset makers Nokia (HMD), Sony, Xiaomi, Oppo, Vivo, HTC, LG, ASUS, and ZTE. Conspicuously absent at the time of this writing is Samsung, though the two companies did just announce a long-term cross-licensing agreement, so you'd have to think they were on track to build a phone with this new modem, too.

Other companies in the list can be found in the press release below, though most of the others are in the component or supply chain side of the business.

Qualcomm's X50 has been undergoing testing and trials at the company internally for some time, and will proceed to operator trials later this year with 18 operators around the world, including AT&T, Verizon, and Sprint here in the US (T-Mobile, oddly, is absent from this list). AT&T says it will launch the US's first mobile 5G NR network in late 2018, Sprint in the first half of 2019, and Verizon plans to continue expansion of its residential 5G trials this year, offering no comment on its plans for a mobile 5G network.
