Huawei, Qualcomm roll out embedded SIM
Huawei has demonstrated a cellular IoT chip that connects to an IoT narrow band network (NB-IoT) using an embedded SIM that complies to the Deutsche Telekom nuSIM standard. Qualcomm has said it will enable Deutsche Telekom’s nuSIM solution on its 9205 LTE modem.

Deutsche Telekom's nuSIM moves the SIM functionality from the physical SIM card directly to the chipset and is 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. Deutsche Telekom's partners in the nuSIM initiative include: Altair Semiconductor, Commsolid/Goodix, HiSilicon, Nordic Semiconductor, Qualcomm Technologies, Samsung Electronics, Sequans Communications.

For the demonstration, Huawei used a Quectel BC95-G IoT communication module based on Huawei's Hi2115 NB-IoT System on Chip (SoC). Using a dedicated nuSIM loader tool, an encrypted operator profile was downloaded to the security processor inside the chip, then decrypted and installed. The device successfully connected to a live NB-IoT network.

"We are now moving towards security certification and look forward to continue working with our partners in the nuSIM community," said Chris Lowe, SIM Technology Lead at Huawei UK R&D, in a statement.

The operator profiles are size-optimized and occupy less than 500 bytes. On Qualcomm's 9205 LTE modem nuSIM is enabled by the Trusted Execution Environment (TEE) based on ARM's TrustZone. The modem is optimized for low power to make it suitable for long-lived and battery operated IoT nodes such as asset trackers, health monitors, security systems, smart city sensors and smart meters, as well as a range of wearable trackers.
