During an investor call on Tuesday, SpaceX announced its plans to build a mobile service network and enter the US market. This will put SpaceX in direct competition with AT&T, T-Mobile and Verizon. SpaceX recently acquired 65 MHz wireless spectrum licenses from EchoStar for $19.6 billion, which will help the company expand its mobile services. Maybe SpaceX wants to pair its Starlink network with a ground-based infrastructure to potentially offer unrivaled coverage across the US. This means it will take decades of solid investment before SpaceX can take a significant chunk of the market in the US.
