SpaceX's recent IPO prospectus positions Starlink Mobile as a direct competitor to terrestrial mobile networks, aiming to provide services "on par" with existing providers, even in urban centers. This ambition marks a significant shift from its current role, primarily serving remote areas as a backup option.
The company's May 20 regulatory filing detailed plans for upgraded satellites and the use of spectrum acquired from EchoStar. These enhancements would dramatically improve services, which currently remain limited to messaging and basic voice and data capabilities. SpaceX anticipates Starlink Mobile will become the preferred connectivity experience for customers across rural, suburban, and urban environments as its constellation grows and performance improves.
This aggressive outlook contrasts with the more conservative stance of telecommunications companies, including T-Mobile, a key mobile network operator (MNO) partner.
T-Mobile CEO Srini Gopalan noted on May 18 that satellite usage accounted for just 0.0002% of total network traffic in May, concentrated in national parks. He emphasized that customers typically purchase satellite service as part of premium packages, not as a standalone offering. T-Mobile's Starlink-powered satellite service is bundled into some premium plans or sold as a $10 monthly add-on, even to rival carrier customers.
Starlink Mobile's Financial Projections and Network Expansion
SpaceX's S1 registration filing showed Starlink Mobile generated $632 million last year from its "mobile connectivity business." This revenue came from partnerships with over 30 MNOs across six continents. The company reported $11.4 billion in revenue for its entire connectivity segment in 2025, which includes services from approximately 9,600 Starlink broadband and mobile satellites in low Earth orbit. SpaceX expects Starlink Mobile to become a major contributor to this segment's revenue as next-generation satellites enhance capabilities.
As of March 31, about 650 V1 Mobile satellites provided satellite-to-mobile texting and over-the-top voice services, such as WhatsApp, to roughly 7.4 million unique devices monthly. SpaceX plans more comprehensive satellite-to-mobile services, including broadband data and Internet of Things (IoT) connectivity, which it expects will deliver "resilient, infrastructure-independent connectivity worldwide and enable 5G connectivity." These advanced services will rely on V2 Mobile satellites, slated for deployment via Starship beginning in 2027. A single Starship launch could carry up to 50 V2 Mobile satellites, a significant increase from the smaller V1 Mobile satellites currently launched on Falcon 9.
Market Opportunity and Regulatory Hurdles
This aggressive outlook contrasts with the more conservative stance of telecommunications companies, including T-Mobile, a key mobile network operator (MNO) partner.
The IPO filing projected a $740 billion total addressable market for Starlink Mobile, close to the $870 billion opportunity identified for Starlink Broadband.
Still, SpaceX assumes a monthly mobile average revenue per user (ARPU) of $8 globally, ranging from $18 in high-income markets to $2 in areas with lower consumer spending power. The company has previously considered a "hybrid satellite/terrestrial network" to extend coverage into buildings, though this was not mentioned in the IPO prospectus.
Expanding Starlink Mobile into denser markets could also raise new spectrum interference concerns. The S1 filing cautioned that global expansion depends on maintaining partnerships with telcos and spectrum licensees, alongside securing country-by-country approvals. In the U.S., SpaceX expects to provide 5G-like connectivity to many existing unmodified devices through its Starlink Mobile Gen2 service using V2 Mobile satellites. This will occur either through spectrum leased from MNO partners or by utilizing its own domestic spectrum holdings. Full 5G NR-NTN compliance and optimal performance, however, would likely require hardware modifications by handset manufacturers.
