New usage data shows AT&T subscribers are tapping into T-Mobile’s Starlink-powered T-Satellite more than expected, signaling a rapid shift in how carriers and customers think about direct-to-device connectivity. Speedtest intelligence indicates T-Mobile users account for the majority of direct-to-device (D2D) connections to Starlink, roughly six in ten overall and more than seven in ten among devices reporting active service at connection time. The surprise is AT&T’s footprint: about a third of observed connections come from AT&T subscribers, while Verizon’s share is minimal.
