Verizon CEO Dan Schulman says SpaceX would need up to $500 billion, 80,000 cell towers and as long as eight years to build a US mobile network that rivals Verizon. Elon Musk hit back on X, saying it "will take 2 or 3 years". SpaceX plans to switch on Starlink Mobile in early 2028 after buying low-band mobile spectrum worth about $8 billion this month.
