### **The Cellular IoT Market in 2025: Scale Over Speed as 4.2 Billion Connections Generate €14.5 Billion in Revenue**
By Marc Kavinsky, Lead Editor at IoT Business News.
The cellular Internet of Things (IoT) market has reached a new plateau defined not by explosive growth in revenue, but by massive scale in connections. According to recent data from Berg Insight, the landscape in 2025 is characterized by a significant number of devices generating relatively modest returns, signaling a transition from early adoption to a mature, utility-like infrastructure business.
**A Growing Market, Under Pressure**
Berg Insight’s 2025 data reveals that global cellular IoT connectivity revenues increased by 5 percent year-over-year, reaching €14.5 billion. While this figure represents healthy growth, it is outpaced by the surge in connected devices. The number of cellular IoT connections rose by 11 percent to 4.2 billion worldwide, accounting for approximately 32 percent of all mobile subscriptions globally.
This disparity between connection volume and revenue growth highlights a key economic shift in the market. The monthly Average Revenue Per User (ARPU) fell by 7 percent to €0.31. In practical terms, this means that while operators are connecting more devices, the average income from each device is decreasing.
**China Dominates the Global Landscape**
The composition of these connections is heavily influenced by the Chinese market. The three largest Chinese mobile operators—China Mobile, China Telecom, and China Unicom—control a dominant share of the global installed base.
* **China Mobile** leads the pack with 1.48 billion connections.
* **China Telecom** follows with 746 million.
* **China Unicom** rounds out the top three with 723 million connections.
Vodafone remains the largest Western carrier with 234 million connections, followed by AT&T (160 million). In a notable surge, Airtel in India demonstrated exceptional growth, with its IoT connections increasing by 115 percent to 69 million.
**Beyond the Numbers: The Rise of Managed Services**
The report also underscores the growing complexity of the IoT ecosystem. Managed Service Providers (MSPs)—companies that manage connectivity for enterprises across multiple networks—have become a critical part of the market. These providers, including names like Aeris, emnify, and SORACOM, managed over 250 million cellular IoT connections at the end of 2025, generating approximately €1.9 billion in annual revenue.
For device manufacturers and enterprises, MSPs offer a solution to the fragmentation of global mobile networks. By providing network-agnostic connectivity via roaming agreements and eSIM profiles, these providers allow devices to operate in multiple countries without needing separate agreements with every local carrier.
**What This Means for the Future**
Looking ahead to 2030, Berg Insight forecasts the cellular IoT market to expand to 6.5 billion devices and €21.5 billion in revenue. For operators, the challenge is clear: success will depend less on the sheer number of SIMs and more on operational efficiency. Profitable growth will require robust systems for billing, remote SIM provisioning, device diagnostics, and roaming management.
For industrial players, utilities, and fleet managers, the takeaway is equally important. Cellular IoT procurement is no longer just about selecting a radio technology. It is now a strategic decision involving long-term service lifecycle management, multinational coverage, and integration with enterprise systems. The winners in this maturing market will be those who make managing large-scale IoT deployments simple and reliable.

### **Frequently Asked Questions (FAQ)**
**Q1: What is the total size of the cellular IoT connectivity market in 2025?**
A1: The global cellular IoT connectivity revenues reached €14.5 billion in 2025.
**Q2: How many cellular IoT connections were there in 2025, and how does this compare to previous years?**
A2: There were 4.2 billion cellular IoT connections worldwide at the end of 2025, representing an 11 percent growth year-over-year.
**Q3: Why is revenue growth slower than connection growth?**
A3: This is due to a decline in the Average Revenue Per User (ARPU), which fell by 7 percent to €0.31 per month. The market is expanding in volume (more devices) but the revenue per device is shrinking, often referred to as a “race to the bottom” on pricing for basic connectivity.
**Q4: Which region accounts for the largest share of cellular IoT connections?**
A4: China accounts for the largest share. The top three Chinese operators (China Mobile, China Telecom, and China Unicom) collectively manage billions of connections, significantly influencing global statistics.
**Q5: Which are the largest mobile operators in the Western world for IoT?**
A5: Vodafone is the largest Western operator with 234 million connections, followed by AT&T with 160 million.
**Q6: What role do Managed Service Providers (MSPs) play in the IoT market?**
A6: MSPs act as intermediaries that manage cellular connectivity for enterprises across multiple mobile networks. They are crucial for simplifying global deployments, using models like roaming agreements and eSIMs to avoid the complexity of dealing with individual carriers in every country.
**Q7: What does the future look like for the cellular IoT market?**
A7: The market is forecast to grow to 6.5 billion devices and €21.5 billion in revenue by 2030. Success for providers will depend on operational efficiency, platform capabilities, and managing large IoT estates rather than simply selling SIM cards.

### **Conclusion**
The data from 2025 paints a clear picture of cellular IoT maturing into a high-volume, low-margin utility business. The era of rapid, revenue-explosive growth is giving way to a focus on scale and operational excellence. While China dominates the connection count, the real story is the structural change in the market’s economics.
For the industry, the path forward requires a shift in strategy. Profitability will no longer come from volume alone but from sophisticated management platforms, efficient lifecycle services, and the ability to provide seamless, global connectivity. As the IoT ecosystem continues to expand, the ability to manage this vast number of devices reliably and cost-effectively will become the ultimate competitive differentiator.
