@shankypanky one of his companies announcing they are working on a hardware device that works on a cell network and can optionally integrate with grok
@strutheo Re above answer: What about
"SpaceX's Starlink Direct to Cell service connects standard mobile phones to satellites, eliminating dead zones by turning satellites into floating cell towers. This service uses existing LTE/4G phones with no special hardware or apps and is expanding to include text, voice, and data, with the ultimate goal of full internet browsing and video calls. SpaceX is partnering with mobile network operators to make this service available."
I would suggest the satellites are a 'hardware device' but perhaps you intended a customer held 'cell phone' device?

Question created 11 Jun 2024
Announced Jan 2024?
SpaceX first announced its direct-to-cell technology for mobile phones in January 2024, coinciding with the launch of its first satellites with this capability.
So perhaps not revealed after this question created.
There has been expansion of service recently to video having started with text only but perhaps this was all revealed prior to question creation:

SpaceX plans to start enabling texting from space this year in partnership with cellular operators, with voice and data connectivity coming in 2025, although the company still needs regulatory permission to provide the services commercially.
