Multi-IMSI has evolved from a simple SIM capability into a dynamic connectivity control layer, where the real value lies in how network identities are selected, managed, and adapted throughout the SIM lifecycle.
In 5G SA, OTA becomes a core network execution layer, enabling Steering of Roaming decisions to be applied directly on the SIM. Through SP-AF, network policies are securely transformed into persistent USIM-level actions.
Simartis uses the Amarisoft AMARI Callbox to validate SGP.32 eSIM IoT workflows in a controlled lab, testing Multi-IMSI logic, constrained radio conditions, and lifecycle scenarios to ensure predictable large-scale deployments.
eSIM IoT (SGP.32) delivers a lifecycle-driven connectivity model for large-scale, long-lived IoT deployments - enabling regulatory compliance, zero-touch onboarding, secure profile switching, and long-term continuity without physical access.
Generic QR codes enable instant, scalable eSIM activation for travel, events, campuses, enterprises, and emergency aid. Operators can deliver seamless mobile connectivity without apps or physical SIMs, ensuring compliance, flexibility, and real-time profile management for diverse use cases.
GSMA SGP.32 introduces a scalable, secure, and fully automated eSIM provisioning model for IoT. Simartis offers a unified SM-DP+ and eIM solution, enabling seamless lifecycle management and flexible deployment across diverse, constrained IoT devices.
The SIMARTIS Polling Applet enables secure, SMS-free SIM updates via HTTPS, ensuring reliable, scalable, and automated SIM management. It’s a future-ready solution for telecom operators adapting to modern network demands.
SIM technology has evolved - from physical cards to eSIM and now iSIM, enabling smarter, smaller, and more efficient connected devices. With remote activation and seamless integration, eSIM and iSIM are transforming how businesses manage mobile connectivity.
