Global Cellular IoT Connections Up 22% to Reach 2.1 Billion in 2021
July 18, 2022 | Berg InsightEstimated reading time: 1 minute

A new report from the IoT market research firm Berg Insight says that the global number of cellular IoT subscribers increased by 22 percent during 2021 to reach 2.1 billion. The major regional markets China, Western Europe and North America grew similarly during the year as the world recovered from the COVID-19 pandemic. By 2026, Berg Insight now projects that there will be 4.3 billion IoT devices connected to cellular networks worldwide.
The top ten mobile operators reported a combined active base of 1.8 billion cellular IoT connections at the end of 2021, accounting for 86 percent of total connections. China Mobile is the world’s largest provider of cellular IoT connectivity services with an estimated 801 million cellular IoT connections. China Unicom and China Telecom ranked second and third with 300 million and 297 million connections respectively.
Vodafone ranked first among the Western operators and fourth overall with 142 million connections, followed by AT&T with 95 million in fifth place. Deutsche Telekom and Verizon had in the range of 45–55 million cellular IoT connections each, when counting T-Mobile USA’s customers as part of DT’s IoT subscriber base. Telefónica, KDDI and Orange were the last players in the top ten with about 31 million, 23 million and 20 million connections respectively. The year-on-year growth rates for the largest operators were in the span of 0–41 percent.
IoT connectivity services account for around 1 percent of total revenues for most operator groups. Berg Insight’s analysis of the IoT business KPIs released by mobile operators in different parts of the world suggests that global IoT connectivity revenues increased by around 15 percent during 2020, while the monthly APRU dropped by 2 percent to € 0.38.
The shift to embedded SIMs, or eSIMs, is currently one of the strongest trends within the IoT connectivity market. Automotive OEMs stand out as early adopters of the technology, which is now experiencing broad uptake across a range of vertical markets. Leveraging the benefits of the two existing eSIM specifications – M2M and Consumer – GSMA’s new IoT specification is set to further accelerate uptake of the technology as it will eliminate the need for integrations between mobile operators and provide greater flexibility for IoT solution providers.

Critical Minerals: The New Power Play in Global Trade
10/13/2025 | Marcy LaRont, I-Connect007Access to critical minerals essential for electronics manufacturing, and China’s monopoly of them, is increasingly under scrutiny, with gallium (Ga) and germanium (Ge)at the forefront of this discourse. However, all critical minerals imported from China share a similar narrative, and understanding the implications of this dependency and the risks to both U.S. commercial and defense sectors has created an urgent need for a comprehensive electronics strategy to secure and diversify access to these vital minerals. In this candid interview, USPAE Executive Director Jim Will discusses the issues and the mitigation steps that must be taken to adequately address them.

09/26/2025 | Marcy LaRont, I-Connect007Though the news cycle felt a little less exclamatory this week, there were many global business news headlines worth revisiting. Among them, China announced a bold carbon emissions goal of 10% over the next decade to double its solar and wind power capacity. The Wall Street Journal published an article, “Global Port Leaders See Trade Shifting, Not Slowing,” a nod to businesses’ risk mitigation strategies and execution around overreliance on China coming into play in a bigger way.
