RMS and eSIM - RMS Credits

The connection

RMS and eSIM integration allows both the device configuration and the SIM profile to be managed remotely from a single platform. A Teltonika device with an eSIM-capable module can receive firmware updates, configuration changes, and SIM profile swaps via RMS – without a site visit or a physical SIM card change.

What eSIM enables in an RMS context

Traditional IoT deployments use physical SIM cards. Changing the SIM – to switch operator, update credentials, or replace an expired SIM – requires a physical site visit. For devices deployed in remote locations, vehicles, or sealed industrial equipment, this is expensive and sometimes impractical.

eSIM (embedded SIM) using eUICC (embedded Universal Integrated Circuit Card) technology allows the SIM profile to be changed remotely, over the air. When combined with RMS for device management, the result is a fully remote management capability: device configuration and SIM profile both managed without physical access.

RMS + eSIM – Remote Management Without Site Visits

SGP.22 and SGP.32

Two eUICC standards are relevant to RMS and IoT eSIM management:

SGP.22 – the GSMA consumer eSIM standard. Supports remote SIM profile download and management via SM-DP+ servers. Already widely implemented in smartphones. Used in some Teltonika devices with consumer-grade eSIM modules.
SGP.32 – the GSMA IoT eSIM standard (formerly M2M eSIM follow-on). Designed specifically for IoT devices with constrained connectivity, asynchronous operation, and integration with IoT device management platforms. The natural evolution for RMS-managed eSIM deployments.

See RMS and SGP.22 and RMS and SGP.32 for technical detail on each standard and how they interact with the RMS platform.
