Deutsche Telekom leads on development of eSIM for IoT


Deutsche Telekom is working with partners to develop nuSIM. The initiative aims to move SIM functionality from the physical SIM card directly to the chipset.

nuSIM is specifically designed for low-cost devices used in mobile IoT applications with a long life-span, such as asset trackers or smart motion or temperature sensors.

The operator has partnered with a range of companies specialising in IoT chipsets, modules and digital security with the aim of making the product commercially available in the second half of 2019.

Why eSIMs?

The elimination of the physical SIM card simplifies the form factor of an IoT device as there are no additional contacts, circuit paths or SIM card holders to consider. Deutsche Telekom says nuSIM will provide a “minimum hardware and software footprint for cost-efficient implementations with minimal power consumption”.

Device vendors benefit from better design options due to smaller package size and extended battery life. SIM logistics, such as stock keeping or handling, are no longer necessary. IoT service providers can save costs through a simple digital process which puts the operator's credentials onto the device during manufacture. Customers also benefit from the lower device cost and greater simplicity

Building block

Ingo Hofacker, Senior Vice President, responsible for the IoT business at Deutsche Telekom, said, “Deutsche Telekom has built a solid track record in IoT technology innovation over the past years. The most important success driver for us is to anticipate customer needs to make sure we enable their business success.

“nuSIM, our rigorously optimised SIM solution for the cost-sensitive mobile IoT market is our latest endeavour and an important building block for our offering moving forward.”
