SpaceX is exploring an acquisition of Boost Mobile from EchoStar as Elon Musk seeks to combine satellite connectivity with terrestrial cellular infrastructure and establish a stronger position in the US wireless market, according to a report by The Washington Post.
A deal would give SpaceX access to Boost Mobile’s existing customer base and potentially expand the reach of its Starlink satellite service through cellular networks. The combination could help the company move towards becoming the fourth-largest wireless provider in the United States, although the transaction would face regulatory and commercial hurdles, including questions over Boost’s existing network agreements.
Musk, SpaceX’s chief executive, reportedly spoke directly with EchoStar chairman Charlie Ergen in October about acquiring Boost Mobile, a mobile virtual network operator (MVNO). EchoStar has approximately 7.5 million customers across Boost Mobile and GenMobile, its other mobile service.

The discussions come as SpaceX broadens its ambitions beyond satellite internet and rocket launches into mobile telecommunications. The company has been developing direct-to-cell services through Starlink, seeking to connect ordinary mobile phones in areas where conventional cellular coverage is unavailable.
SpaceX began offering satellite connectivity to T-Mobile subscribers in 2024. The partnership provided an early route into the mobile market without requiring SpaceX to build a nationwide terrestrial network of its own.
SpaceX’s interest in Boost Mobile follows its $17 billion acquisition of wireless spectrum from EchoStar last year, a transaction intended to strengthen its ability to deliver cellular services.
The spectrum could help Starlink address one of the limitations of satellite connectivity – its difficulty reaching devices inside buildings and other locations where satellite signals are obstructed. Terrestrial cellular infrastructure would provide another layer of coverage, allowing SpaceX to combine satellite and ground-based networks rather than depend exclusively on signals travelling from space.
At the time of the spectrum acquisition, Musk described the deal as the final major component needed to provide comprehensive mobile coverage in the United States.
“This is the last critical piece of the spectrum puzzle needed for SpaceX to provide complete phone coverage in America,” he said on X.
The reported interest in Boost Mobile suggests that owning spectrum alone may not be sufficient to deliver the coverage and reliability SpaceX wants. Spectrum provides the frequencies required to transmit wireless signals, but a nationwide mobile service also depends on network infrastructure, customer relationships and access to existing cellular capacity.
Boost Mobile could provide an immediate route into that ecosystem. Its existing subscribers would give SpaceX a customer base, while its network arrangements could offer access to terrestrial coverage that would take considerable time and investment to build independently.
Network Agreements Could Complicate the Deal
The acquisition would not automatically give SpaceX unrestricted access to the cellular infrastructure currently used by Boost Mobile.
Unlike AT&T, T-Mobile and Verizon, Boost does not operate its own nationwide network of mobile towers. It leases capacity from AT&T and T-Mobile to provide service to its customers. Those arrangements are therefore key to the value of any potential acquisition.
Musk has reportedly approached AT&T, T-Mobile and Verizon about purchasing capacity on their networks, but all three companies rejected the proposals.
The existing agreements between Boost and its network providers could also complicate a change of ownership. Sources cited by The Washington Post said network leases are generally nontransferable, meaning AT&T and T-Mobile might need to approve any arrangement that allows SpaceX to continue using their capacity after an acquisition.
That situation has created a notable distinction between purchasing a mobile operator and securing the infrastructure required to serve its customers. SpaceX could acquire Boost’s customer relationships and business operations, but maintaining the same level of network access may depend on agreements with companies that have already declined to sell capacity directly to Musk.
The three largest US wireless providers each have more than 100 million subscribers, substantially larger than Boost Mobile. An acquisition would therefore not immediately put SpaceX on comparable footing with the established operators. Its significance would lie more in the opportunity to combine satellite coverage, spectrum holdings, and terrestrial network access into a single service.
The potential commercial advantage is the ability to use different networks according to where a customer is located and which signals are available.
Starlink could provide connectivity to compatible devices outdoors and in areas beyond the reach of conventional mobile infrastructure. Cellular towers could handle connections in locations where satellite signals are obstructed or unavailable, including some indoor environments.
Boost Mobile currently provides coverage across most of the 48 contiguous US states through its network arrangements. Access to that footprint could significantly expand the geographical reach of SpaceX’s mobile ambitions.
The strategy could also give SpaceX a more direct relationship with mobile subscribers, rather than relying primarily on partnerships with established wireless operators to distribute satellite connectivity.
For the US telecommunications market, the potential acquisition signals a further convergence between satellite communications and conventional mobile services. Satellite operators are seeking to extend connectivity beyond areas served by ground infrastructure, while established wireless companies are exploring partnerships to fill coverage gaps.
