SpaceX has expanded its cellular Starlink satellite count from six to 38, with the system currently undergoing testing. Despite being in its testing phase, the technology proved capable enough to facilitate a successful video call.
In a recent demonstration shared on Twitter, SpaceX conducted the first video call through Starlink Direct to Cell satellites using unmodified mobile phones. The demonstration, seemingly held at SpaceX’s Redmond, Washington offices, displayed an employee connecting their smartphone to SpaceX’s cellular Starlink satellites orbiting hundreds of kilometers away. Despite the distance, the smartphone established a connection and accessed the video call feature.
Although the resulting call transmitted video footage over the cellular Starlink network, the image quality appeared slightly grainy, and the clip was brief. Nonetheless, the phone initiated a call with another smartphone connected to a traditional cellular network.
First video call on @X completed through @Starlink Direct to Cell satellites from unmodified mobile phones!
We’re excited to go live with @TMobile later this year 🛰️🌎 pic.twitter.com/v4nA5B75EX

SpaceX’s progress in cellular Starlink technology follows the recent increase in satellite numbers, from six in January to 38 last week, according to SpaceX Senior Director Ben Longmier. Previous tests in March demonstrated the tech’s ability to deliver download speeds of up to 17Mbps to unmodified Android phones.
Later this year, SpaceX intends to launch the cellular Starlink service, initially targeting T-Mobile customers. This service aims to provide connectivity in remote regions where traditional cell towers are absent, with SpaceX’s satellites effectively serving as space-based cell towers.
Before launching the service in the US, SpaceX awaits FCC approval. The recent video call demonstration may serve as an effort to persuade US regulators to approve the technology for commercial use. However, rival company Omnispace has raised concerns about radio interference caused by SpaceX’s cellular Starlink system, urging the FCC to intervene. As of now, the FCC has not commented on the matter.
