u-blox has introduced the SARA-R10001DE, an LTE Cat 1bis module with integrated eSIM featuring multi-IMSI technology and eUICC functionality. The module is pre-provisioned with Wireless Logic’s Conexa IoT Network SIM profiles for global IoT deployments. The eSIM supports OTA using Remote SIM Provisioning, allowing the module to switch between multiple stored SIM profiles to connect to the best available network.
Multi-IMSI technology allows eSIMs to store multiple International Mobile Subscriber Identity (IMSI) profiles, enabling dynamic network switching for uninterrupted connectivity. eUICC functionality, based on the GSMA standard, facilitates OTA updates and profile management, simplifying operator switching and ensuring global compliance.
Although SARA-R10001DE is u-blox’s first LTE Cat 1bis module with an embedded SIM (eSIM), we previously covered the u-blox LEXI-R10 LTE Cat 1bis module and associated evaluation kit, as well as Cavli C17QS Cat 1bis module built around the Qualcomm QCX217 microcontroller.

The SARA-R10001DE is a professional-grade LTE Cat 1bis module designed for global connectivity and migration from legacy 2G, 3G, and LPWA devices to 4G LTE networks. It supports dual-stack IPv4/IPv6, MQTT, TCP/IP, UDP/IP, HTTP, and TLS/DTLS protocols, and the module is GSMA SGP01/02 compliant for remote SIM provisioning and firmware updates via FOAT and FOTA. The company can also provide the EVK-SARA-R10001DE evaluation kit, but no publicly available information is available at this time.
u-blox has not disclosed pricing details for its LTE Cat 1bis module with eSIM yet. For more information, refer to the product page and the official press release.
