SpaceX's recent IPO prospectus outlines Starlink Mobile's ambition to compete directly with terrestrial mobile networks, extending its services beyond remote areas into urban centers. The May 20 regulatory filing details plans for next-generation direct-to-smartphone services, aiming for performance "on par with terrestrial mobile networks" across various environments.
The company plans to upgrade satellites and utilize spectrum acquired from EchoStar to enhance current services, which are largely limited to messaging, light voice, and data. SpaceX noted that while Starlink Mobile currently serves remote areas, its growing constellation and improved product performance will target customers in rural, suburban, and urban settings.
Starlink Mobile's Market Vision and Telco Relations
This aggressive market strategy contrasts with the more conservative views of traditional telcos.
T-Mobile, a key partner providing wireless spectrum for Starlink Mobile's current U.S. coverage, reported that satellite usage accounted for just 0.0002% of its total network traffic in May, concentrated in national parks. T-Mobile CEO Srini Gopalan emphasized that most customers acquire satellite service as part of premium packages offering broader benefits like global roaming or ad-free Netflix.
T-Mobile's Starlink-powered satellite service is bundled with some premium plans or available as a $10 monthly add-on, even for customers of rival carriers. The company recently explored a joint venture with AT&T and Verizon to enhance direct-to-device capabilities through shared spectrum and standardized services. SpaceX executives, however, have criticized this potential joint venture, raising questions about regulatory scrutiny of coordination among the three largest U.S. wireless carriers.
Financials and Future Capabilities
SpaceX projects Starlink Mobile will significantly contribute to connectivity segment revenue as next-generation satellites improve capabilities.
The Information reported last month that T-Mobile agreed to pay SpaceX $100 million over several years for Starlink Mobile services, contingent on specific milestones. SpaceX's S1 registration filing indicated its "mobile connectivity business" generated $632 million last year, partnering with over 30 mobile network operators across six continents. The company's entire connectivity segment recorded $11.4 billion in revenue for 2025, encompassing broader services from its approximately 9,600 Starlink broadband and mobile satellites in low Earth orbit.

As of March 31, about 650 V1 Mobile satellites provided satellite-to-mobile texting and over-the-top voice services, reaching roughly 7.4 million unique monthly devices. More comprehensive satellite-to-mobile services are under development, including broadband data and Internet of Things (IoT) connectivity, designed to offer resilient, infrastructure-independent global connectivity and enable 5G. These advancements will rely on V2 Mobile satellites, which SpaceX plans to deploy using Starship starting in 2027. A single Starship launch could carry up to 50 V2 Mobile satellites, a substantial increase from the smaller V1 Mobile satellites currently launched on Falcon 9.
The IPO filing estimates a $740 billion total addressable market for Starlink Mobile, approaching the $870 billion TAM projected for Starlink Broadband. SpaceX anticipates 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 S1 filing cautioned that global expansion of Starlink Mobile hinges on maintaining partnerships with telcos and spectrum licensees, alongside securing country-by-country regulatory approvals. In the United States, SpaceX expects to deliver 5G-like connectivity to many existing unmodified devices via its Starlink Mobile Gen2 service and V2 Mobile satellites, using either leased spectrum from MNO partners or its own domestic spectrum holdings.
