From SOS to Direct Internet: Why satellite D2D is becoming the next mobile coverage layer

Satellite direct-to-device (D2D) connectivity is evolving from emergency messaging to a mainstream mobile coverage layer, with significant market growth projected from USD 0.38 billion in 2025 to USD 27.7 billion by 2035, driven by expanding services from SOS alerts to messaging, voice, and direct internet, supported by regulatory approvals, operator partnerships, and increasing device compatibility, particularly in North America and Europe.

The satellite direct-to-device market has crossed an important threshold. For years, the industry asked whether ordinary phones could connect directly to satellites without a special terminal, dish, or satellite phone. That question is now being answered in the market. The more important question is what comes next: which services monetize first, which regions scale fastest, and which companies control the customer relationship. Recent developments show that D2D is becoming a strategic telecom layer, not a niche satellite feature. In May 2026, Verizon, AT&T, and T-Mobile agreed in principle to form a joint venture focused on using satellite-based direct-to-device technologies to reduce rural dead zones and improve backup connectivity during disasters. In the same week, the FCC approved EchoStar's sale of spectrum to SpaceX and AT&T, including 65 MHz to SpaceX to support Starlink's next generation device-to-device offering. In Europe, Ofcom has also moved from policy discussion to implementation, with license variations and handset exemption rules that allow D2D services using mobile spectrum bands in the UK. These updates reinforce the signal: satellite connectivity is bein...
