Redtea Mobile Engages in Joint Effort to Implement nuSIM for IoT

Tuesday 30 Jun 2020 | Member Press Release |

[Singapore, June 25, 2020] Redtea Mobile, the pioneering connectivity solution provider has engaged in the joint effort to introduce nuSIM, the integrated SIM for IoT, which brings clear benefits for costs, power consumption and overall design simplicity by fully integrating the SIM functionality on a chipset.

The joint solution was developed in accordance with Deutsche Telekom’s open nuSIM specification and consists of a trusted application from Redtea Mobile in a Quectel BG95 module containing a Qualcomm® LTE 9205 chipset. The integrated nuSIM will be an important enabler, in particular for cost-efficient devices used in mobile IoT applications with a long lifespan, such as asset trackers or smart sensors.

“We are honored to work with leading industry players including Deutsche Telekom, Qualcomm Technologies, and Quectel to provide an innovative new means to simplify the deployment of ubiquitous connectivity in the IoT space,” said Xiaodong Guo, VP of Strategic Partnerships & Projects at Redtea Mobile. “Redtea Mobile is on a mission to simplify connectivity for a more productive world. By moving the SIM function into the chipset, mobile operator data is added through a secure process step at the time of module or device manufacturing and the end-customer gets instant connectivity without any additional actions.”

“Since introducing the nuSIM initiative at the beginning of last year, Deutsche Telekom has been working with various industry leading partners, including Redtea Mobile, on the basis of an open and interoperable specification,” said Stefan Kaliner, Head of UICC Development at Deutsche Telekom. “The trusted application developed by Redtea Mobile is the nuSIM OS, which provides the functionality to receive and process an encrypted nuSIM profile so that the result behaves exactly like a classical SIM.”

“The addition of Redtea Mobile’s trusted application as part of the integrated nuSIM solution on the Qualcomm 9205 LTE modem, leveraging the Qualcomm® Trusted Execution Environment, will help further support reliable, secure and optimized cellular connectivity for IoT applications globally,” said Vieri Vanghi, Vice President, Product Management, Qualcomm Europe, Inc. “We are proud of our collaboration with Redtea Mobile, Quectel and Deutsche Telekom as it will help drive increased adoption of nuSIM technology, which is necessary to develop the next generation of secure, cost-efficient and low-power IoT devices.

“Quectel Wireless Solutions has securely integrated the Qualcomm 9205 LTE Modem and nuSIM OS into our BG95-M3 LTE Cat M1/Cat NB2/EGPRS module to create an ultra-low power product,” concludes Dominikus Hierl, SVP EMEA at Quectel Wireless Solutions. “The result is ideally suited for a wide range of IoT applications such as wireless POS, smart metering, tracking, or wearable devices, where the removal of the physical SIM component helps to reduce device size and save on cost and power consumption.”
