In response to the market leader, competitors backed by industry giants AT&T and Verizon accelerated their own D2D strategies. AST SpaceMobile is pursuing a more ambitious goal of providing full D2D broadband, a move designed to leapfrog the initial messaging-focused services offered by rivals. Their strategy hinges on delivering a satellite-based service that more closely mimics a terrestrial cellular experience.
To achieve this goal, the company is aggressively scaling up satellite manufacturing, with plans for a 2026 launch of an intermittent nationwide service. This approach represents a significant gamble, betting that a more robust, data-capable network will ultimately capture the market, even with a later entry. The success of this venture could redefine D2D capabilities from a simple messaging add-on to a genuine broadband alternative.
Omnispace and Lynk Global A Merger for a Standards-Based Platform
The market also showed clear signs of maturation with the significant merger of Omnispace and Lynk Global. This consolidation points toward an industry-wide push for interoperability and standardized solutions, moving away from the initial wave of proprietary, closed-network approaches. The creation of a larger, more integrated entity suggests a more collaborative future for D2D development.
The newly formed entity, with a strategic investment from SES, aims to create a comprehensive, standards-based D2D platform. By utilizing Omnispace’s globally coordinated S-band spectrum, it intends to offer a robust alternative to proprietary networks. This initiative promises to provide MNOs worldwide with a more flexible and open framework for integrating D2D services into their existing network infrastructure.
Emerging Trends and Market Maturation
The overarching trend of 2025 was the establishment of D2D as a “cost of doing business” in the mobile industry, particularly in North America. Its value proposition rapidly shifted from being a novel, auxiliary revenue stream to a critical tool for customer retention. For carriers, offering D2D became less about direct profit and more about preventing customer churn to competitors who provided it.
This dynamic forced nearly every major carrier, including cable operators expanding into mobile services, to develop and integrate a D2D strategy to remain competitive. The technology’s inclusion in premium plans also served as a powerful upsell mechanism, bundling universal connectivity with higher-tier subscriptions. Consequently, D2D became a strategic necessity for maintaining market position and enhancing brand value.
Global Deployments and Regional Dynamics
The North American Competitive Arena
The U.S. market quickly became the primary battleground for competing D2D services, with T-Mobile’s early launch setting a fast pace for the rest of the industry. The subsequent race to offer comparable or superior services intensified competition among the major MNOs, making D2D a key differentiator in marketing campaigns and a central topic of strategic planning.
Underscoring the technology’s new status as an essential feature, cable operators like Comcast’s Xfinity Mobile and Charter’s Spectrum Mobile entered the fray by partnering with Skylo. This move by mobile virtual network operators (MVNOs) to integrate D2D messaging demonstrated that satellite connectivity was no longer an exclusive feature for major network owners but a standard expectation for any mobile provider seeking to compete effectively.
Europe’s Drive for D2D Sovereignty
In parallel, Europe actively pursued its own D2D capabilities to ensure regional autonomy and avoid dependence on American technology providers. Key developments included Virgin Media O2’s partnership with Starlink for UK coverage and Orange’s preparations to launch the continent’s first D2D services. These initiatives reflect a broader geopolitical aim to cultivate a self-sufficient digital ecosystem.
Furthering this goal, the SatCo joint venture between Vodafone and AST SpaceMobile advanced its plans to create a European-based alternative to U.S. dominance. While promising, this effort faces unique regional challenges. However, the commitment from major European operators signals a strong and coordinated push to establish a competitive, sovereign D2D infrastructure.
Prevailing Challenges and Industry Hurdles
Overcoming Regulatory and Spectrum Fragmentation
While the technology proved viable in commercial deployments, significant challenges remain, particularly in Europe. The continent’s fragmented spectrum landscape presents a complex regulatory hurdle for operators. Unlike the more unified regulatory environment in the United States, deploying seamless, pan-European D2D services requires navigating the distinct policies of numerous individual nations.
This regulatory complexity threatens to slow down deployment schedules and increase operational costs for D2D providers in Europe. Achieving the kind of ubiquitous, cross-border coverage seen in North America will require substantial coordination among national regulators and a concerted effort to harmonize spectrum allocation for satellite services, a process that could take considerable time and negotiation.
The Challenge of Monetization Beyond Basic Messaging
With D2D messaging rapidly becoming a standard offering included in premium plans, the industry’s focus has shifted to a critical question: how to effectively monetize services beyond basic emergency texts. As the feature becomes commoditized, its potential as a direct revenue driver diminishes, forcing operators to look for new value propositions.
