Coming on the heels of an announcement that Samsung will offer a 5G phone on Verizon next year, AT&T has announced that it will also offer the same 5G flagship from the Korean phone manufacturer sometime in spring 2019.

That makes the upcoming Samsung phone the second 5G device for AT&T, following the already-announced Netgear Nighthawk 5G Mobile Hotspot “puck” that the carrier will launch its network with. Qualcomm’s Snapdragon Tech Summit starts today, so odds are we’ll hear more about the hardware that will likely power that Samsung phone soon.
