SpaceX advances Starlink Direct to Cell testing across major smartphone brands
SpaceX has shared with the US Federal Communications Commission that its Starlink satellites have undergone successful testing with Direct to Cell technology, a breakthrough that would enable ordinary smartphones to connect directly to Starlink satellites. This update comes through reports picked up by the PCMag portal.
In the FCC filing, SpaceX notes that the satellites communicated with a range of smartphones from Samsung, Apple, and Google Pixel. The tests used T-Mobile’s PCS G Block spectrum and demonstrated connectivity in diverse environments, including urban corridors, suburban and rural expanses, indoor settings, outdoor spaces, and wooded areas. The company reported that data transmission continued without interference from nearby devices so long as the satellite remained visible in the sky.
SpaceX stressed that Starlink Direct to Cell would enable internet data to reach smartphones inside buildings, a feature that could change how people access online services from indoors. While specific technical details were not disclosed, the company stated that tests occurred within the maximum permissible power flow density. Elon Musk’s firm also pushed back against claims from other telecom and satellite providers that Starlink’s cellular satellites might cause radio interference.
Looking ahead, SpaceX plans to roll out Starlink satellite cellular service to T-Mobile customers within the year, contingent on FCC approval. The initial phase is expected to support SMS messaging, with voice calls and full Internet access to follow in the next year. The roadmap includes launching more than 800 satellites equipped for Direct-to-Cell operation to realize this service at scale.
Context for this development notes prior observations by other satellite phone initiatives. For instance, the Thuraya SkyPhone, paired with Android 14, has been noted to be operable in Russia under certain conditions. This historical reference helps illustrate the broader interest in integrating satellite connectivity with mainstream mobile devices.
