Elon Musk's SpaceX is accelerating its push into the U.S. mobile communications market. On November 4, Qualcomm announced a multi-year partnership with SpaceX to supply 5G cellular network infrastructure technology for Starlink Mobile, helping it build a nationwide terrestrial mobile communications network in the United States. This signals that SpaceX is no longer content with offering limited direct-to-phone service via satellite; instead, it plans to establish a full-fledged mobile network capable of competing head-on with Verizon, AT&T, and T-Mobile.
