IoT security and the role of eSIM
Enterprises continue to deem security among the top three challenges to IoT adoption (along with integration with legacy systems and cost), according to our Enterprise in Focus Survey. The fragmentation of the IoT ecosystem makes securing IoT a difficult task. As IoT scales so does the surface of attack, which already encompasses a vast ecosystem of devices, communication protocols, platforms and applications. True end-to-end security is difficult to achieve, especially when taking into account the IT/OT and cost requirements. Yet, enterprises view device-to-cloud security as the most important criteria when evaluating an IoT solution's security features.
In this report, we examine how eSIM can address some of the challenges around IoT security. We also highlight a range of vendors offering IoT security solutions, including connectivity and software providers, and security specialists.

Industry Checkpoint: consumer eSIM, Q1 2026
This edition of the Industry Checkpoint series focuses on consumer eSIM, highlighting how the market has changed in the last six months and its implications. The report considers four major developments: how eSIM-only and China’s eSIM launch are two factors that could accelerate consumer adoption of eSIM; how new customer propositions and offerings are taking travel eSIM to the next level; how eSIM is tapping into new categories of emerging consumer devices while driving new bundling approaches; and how eSIM is enabling a better blend of connectivity and entertainment experiences in sport.
Consumer eSIM: device and MNO service trackers, and 2030 adoption forecast, Q1 2026
With eSIM penetration in the consumer market set to double in 2026, and double again in 2027, this tracker provides data that operators, OEMs, eSIM vendors and other companies involved in the eSIM value chain, can use to formulate or adjust eSIM commercial strategies and offers. It covers three main areas: the commercialisation of eSIM consumer devices by OEM brand and type of device (smartphone, tablet and smartwatch); countries and MNOs that have launched commercial eSIM service for smartphones; and a consumer adoption forecast for eSIM in the smartphone market to 2030 (global and regional figures).
IoT in a post-quantum world: coming sooner than you think
The benefits of quantum computing come from the order-of-magnitude increase in computational power compared to conventional computers. This enables a range of use cases from predictive analytics to pharmaceutical simulations. However, there are also risks, primarily related to security vulnerabilities. Overall, we estimate around 8% of IoT devices currently in active use are quantum safe. Conversely, over 90% (i.e. nearly all) of IoT devices are exposed. The exposure risk for telcos comes at multiple levels, including networks, billing systems, consumer devices and IoT. The focus in this report is on the IoT dimension because it represents the largest universe of devices, is highly disparate and is particularly open to security risks due to the ageing nature of many assets deployed today.
