The Shifting Mobile Landscape

The global mobile telecommunications sector has long served as the backbone of modern digital communication, with mobile network operators (MNOs) traditionally holding a dominant position as the primary gateways to connectivity. However, the rise of over-the-top (OTT) services—from messaging platforms to video streaming and voice applications—has fundamentally disrupted the revenue models that carriers once relied upon. While precise, universally agreed-upon figures on OTT's displacement of traditional carrier revenues remain elusive, industry observers widely acknowledge that the value chain in mobile communications has shifted decisively toward software-based service providers. This dynamic raises urgent questions about whether legacy carriers can adapt quickly enough to remain relevant in an increasingly app-driven ecosystem.

Legacy MNO Business Models Under Strain

Multinational mobile network operators (MNOs) emerged rapidly in the early 1990s and dominated their industry for roughly a decade and a half, as documented in studies of operators like Telenor. Their traditional business models centered on scale, scope, and the control of network infrastructure—approaches now scrutinized for their scalability, replicability, and long-term sustainability. The telecom network ecosystem has grown increasingly complex, with diversified deployment scenarios, multi-standards environments, and multi-vendor support creating operational challenges that legacy frameworks struggle to address. Furthermore, the standards landscape itself has fragmented, with hundreds of informal industry supplements to formal standard-setting organizations complicating governance and innovation.

From Circuit-Switched Monoliths to Packet-Switched Disruption

The history of telecommunications traces a trajectory from state-owned narrowband circuit-switched networks to privately operated broadband packet-switched infrastructure—a transition made possible by advances in transistor technology and the semiconductor industry. This evolution drove significant declines in the price of telecommunications services and opened the door for new entrants, including the OTT providers that would later challenge carrier dominance. The Library of Congress and the Telecommunications History Group have both documented this arc as a story of continuous technological democratization. What began as government monopolies gradually gave way to competitive private markets, setting the stage for the current era in which software-based services threaten to supplant the network operators that built the physical layer.

The OTT Invasion: Quantifying the Impact on Mobile Carrier Revenue

Smartphone apps floating above city with telecom towers

Research shows a significant hidden revenue loss for the global telecommunications industry due to the rise of OTTs. This loss is directly correlated with the evolution of OTT services, which now dominate the digital landscape. The study pinpoints SMS as the most impacted traditional service and predicts its near-total disappearance by the end of 2022.

To fully grasp this issue, let's break down the core areas affected:

  • LDC (Long Distance Calls): OTT apps like Skype and WhatsApp have slashed international call revenue for MNOs by offering free or low-cost alternatives.
  • SMS (Short Message Service): The convenience and added features of OTT messaging have rendered SMS virtually obsolete.
  • Voice Calls: While not declining as rapidly as SMS, traditional voice call revenue is still under pressure from OTT voice services.
  • Data Traffic: Although MNOs benefit from increased data traffic due to OTT usage, they struggle to effectively monetize this surge, as OTTs use their infrastructure without contributing to its cost.

Industry Intelligence Points to Cloud-First Transformation

Leading telecom research organizations—including Juniper Research, ABI Research, and GSMA Intelligence—consistently emphasize that 2025 marks a pivotal year for the telecommunications industry, with rapid changes reshaping how networks are managed, services are delivered, and customers choose providers. A 2025 Mobile World Live industry survey highlights that the transition to cloud-first networks is fundamentally reshaping the telecom landscape, creating opportunities for operators to move beyond pure connectivity into cloud services that drive engagement and new revenue streams. These research bodies collectively point to a future where carriers must evolve from being infrastructure providers to becoming platform companies.

The 5G Monetization Problem

Despite the massive capital expenditure required for 5G network rollouts, the telecom industry has struggled to monetize the technology—a problem widely described as one of the sector's most significant failures. Industry leaders surveyed by Telecoms.com cited lackluster returns on costly 5G deployments as their single biggest challenge. Beyond revenue shortfalls, carriers face a convergence of operational pressures including rising cybersecurity threats, the need for responsible AI deployment, growing regulatory burdens, and acute talent shortages. These compounding challenges suggest that simply upgrading network infrastructure is insufficient without a fundamental rethink of how value is captured in the OTT-dominated era.

MNOs vs. MVNOs: A Changing Competitive Dynamic

The United States mobile market illustrates the evolving competitive landscape, with approximately 30 facilities-based wireless service providers listed by the CTIA alongside over 50 virtual operators (MVNOs) that resell network access from major carriers. GSMA Intelligence provides global data confirming that this layered competitive structure is replicated across major markets worldwide. Research from Verified Market Research highlights that MVNOs represent a significant pivot in the industry, offering consumers viable alternatives to traditional providers through cost-effectiveness, flexibility, and superior customer service. This structural shift challenges the notion that owning physical network infrastructure guarantees competitive advantage in an era increasingly defined by service differentiation.

The trend is clear: MNOs are investing more to support growing user numbers and traffic, but their Average Revenue Per User (ARPU) is declining. This indicates a fundamental shift in how telecom services are consumed and monetized.

Seize the Future: Recommendations for MNOs

The rise of OTT presents both a threat and an opportunity for MNOs. By understanding the changing landscape, implementing strategic changes, and prioritizing customer needs, MNOs can navigate this disruption and thrive in the digital age. It's time to take a proactive approach and reclaim your position as a vital player in the global communications ecosystem.

Operators Hedge Bets Across Five Technology Fronts

A GSMA Mobile World Live survey of executives from 119 global network operators reveals that carriers are simultaneously investing across five key technology areas: 5G standalone architecture, artificial intelligence and machine learning, open radio access networks (O-RAN), and cloud computing. This multi-front approach suggests that operators recognize no single technology will be a silver bullet against OTT disruption. The emphasis on AI/ML and cloud capabilities in particular signals a strategic pivot toward becoming data-driven service platforms rather than mere connectivity providers.

2026: Flanker Brands and AI-Driven Economics

Deloitte's 2026 telecommunications outlook identifies three emerging themes, chief among them the evolution of 'flanker brands'—secondary brands used by operators to target new segments—into strategic, digital-first growth engines designed to sharpen segmentation, reduce churn, and protect flagship brands. PwC's global telecom outlook for 2025–2029 reinforces this, noting that AI infrastructure investment is reshaping telecom economics and that operators can protect margins by monetizing connectivity and reinventing business models. StartUs Insights reports that 90% of telecom companies are now using AI for network automation, with AI-powered solutions reducing operational expenses by an estimated 30%. Market projections from Data Insights Market suggest the mobile network operator market could reach $2.8 trillion by 2033, driven by 5G expansion, data consumption growth, and IoT proliferation.

Risk Landscape: Trust, Talent, and Regulation

EY's analysis of the top risks facing telecommunications in 2025 identifies trust and talent issues as leading concerns, with cybersecurity threats escalating alongside the need for responsible AI governance and digital skills development. This follows a similar risk profile identified in EY's 2024 assessment, suggesting these challenges are structural rather than transient. Industry analysts also point to heavy regulation as a significant burden—one designed to protect consumers and ensure fair competition, but one that also constrains operators' ability to innovate and pivot as quickly as their OTT competitors. These systemic pressures compound the competitive threats carriers face from both within and outside the traditional telecom ecosystem.

The End-User Experience in a Post-Carrier World

While much of the discourse around OTT disruption focuses on technology and business models, the ultimate question is how these shifts affect everyday consumers. The transition from carrier-controlled services to app-based alternatives has given users more choice, lower costs, and greater convenience—but also introduced new dependencies on a small number of dominant platform companies. As carriers increasingly become 'dumb pipe' providers of raw connectivity, consumers may find themselves trading one set of gatekeepers for another, raising important questions about digital equity, data privacy, and the long-term sustainability of the open internet.

What the findings imply about MNO exposure

The study describes OTT substitution as a pressure on traditional services alongside greater data traffic, so the shift is not simply a loss of use: demand is moving toward services carried over MNO networks.[1]

Limits the evidence itself points to

  • Some country revenue-growth trends used in the research do not align with GSMA global MNO market data, which complicates comparison across sources.[2]

Questions the revenue analysis leaves open

  • How much of the decline in traditional-service revenue is offset by data-service sales for MNOs in different markets?[3]
  • How should an operator’s response change when the degree of service overlap or the size of an OTT provider differs?[1]

Everything You Need To Know

1

What are Over-The-Top (OTT) services, and how are they affecting mobile network operators (MNOs)?

Over-The-Top (OTT) services like WhatsApp, Facebook, and Netflix provide communication and media services directly to users over the internet, bypassing traditional mobile carrier networks. This affects mobile network operators (MNOs) because these services erode traditional revenue streams from services like SMS and voice calls, as users increasingly opt for the free or low-cost alternatives offered by OTT providers. While OTT services increase data usage, MNOs struggle to monetize this effectively, leading to declining Average Revenue Per User (ARPU).

2

Why is SMS revenue declining for mobile network operators (MNOs)?

SMS revenue is declining for mobile network operators (MNOs) primarily due to the rise of Over-The-Top (OTT) messaging services like WhatsApp and Facebook Messenger. These OTT apps offer more features, such as group chats, multimedia sharing, and sometimes even end-to-end encryption, at little to no cost to the user. This increased convenience and functionality makes OTT messaging a more attractive alternative to traditional SMS, leading to a rapid decrease in SMS usage and revenue for MNOs.

3

How do Over-The-Top (OTT) services impact mobile network operator (MNO) revenue from long-distance calls (LDC)?

Over-The-Top (OTT) services significantly reduce mobile network operator (MNO) revenue from Long Distance Calls (LDC). Applications like Skype and WhatsApp offer free or low-cost international calls over the internet, which bypasses the traditional long-distance calling infrastructure of MNOs. This shift to OTT voice services means users are less reliant on MNOs for international communication, severely impacting the revenue generated from these calls. The traditional charging models for long distance calls cannot compete with OTT data based charging and free calls.

4

What are some strategic changes mobile network operators (MNOs) can implement to address the challenges posed by Over-The-Top (OTT) services?

Mobile network operators (MNOs) need to adapt and innovate to address the challenges from Over-The-Top (OTT) services. MNOs should reduce operational costs by modernizing their infrastructure and networks. They can develop customer-centric strategies by bundling services, offering customized data plans that cater to OTT usage, and improving customer experience. Exploring new revenue streams like content delivery, IoT services, and strategic partnerships with OTT providers could allow MNOs to remain competitive and relevant.

5

How can mobile network operators (MNOs) benefit from the increased data traffic generated by Over-The-Top (OTT) services?

While Over-The-Top (OTT) services do not directly contribute to the cost of mobile network operators (MNO) infrastructure, MNOs can benefit from the increased data traffic in several ways. MNOs can offer tiered data plans optimized for video streaming or social media. Another possibility is to offer zero-rated data plans for specific OTT services as part of a premium subscription. MNOs could explore Content Delivery Networks (CDNs) or edge computing services to improve the delivery of OTT content, charging OTT providers for enhanced performance and network efficiency. Effectively managing and monetizing the surge in data traffic could help MNOs offset the revenue loss from traditional services.
