SIMbae™ SIM Based Application Engine
A new way to solve enterprise connected device challenges. See it in action.
SIMbae Overview
IoT Challenges — and How SIMbae Helps
SIMbae™ transforms any SIM, eSIM, eUICC into an intelligent software agent for next-gen connectivity and control.
SIMbae enables context-aware connectivity orchestration directly within the SIM/eSIM secureelement, allowing organizations to enforce deterministic, non-overridable cellular networkbehavior across public, private, and satellite environments — using contextual inputs such asWi-Fi presence and other environmental signals — without reliance on device operating systems,applications, cloud-based intelligence, or user intervention.
From roaming and autonomous monitoring of Quality of Service to on-SIM automation, SIMbae’s preloaded capabilities ensures devices stay reliably connected—at scale, in motion, and across networks.
Protect your existing SIM investments – SIMbae™ allows you to emulate current applet functionality through configurable scripts, while giving developers the option to layer unique features on top of a unified, intelligent framework. Our patented “super applet ” technology unifies roaming, security, monitoring, and automation into one customizable solution-updated securely over-the-air.
The result: Transform your SIMs into a sovereign, programmable control plane that enablesdeterministic network and identity orchestration across hybrid connectivity environments. SIMsnow actively optimize connectivity, strengthen security, and enable new revenue streams—without the complexity
Why SIMbae™?
New! Deterministic Network Switching & Real-Time Rejection Intelligence
SIMbae enhances its context-aware orchestration with powerful new capabilities — all executed
directly within the SIM and managed over-the-air.
Deterministic Network Switching
Automatically transition between public, private, and satellite networks based on real-time
network and radio context — with signal validation and automatic reversion to ensure reliable
connectivity.
Real-Time Network Rejection Intelligence
Gain direct visibility into network rejection events across 2G–5G. When a device is rejected,
SIMbae captures key context — including MCC, MNC, LAC/RAC/TAC, and the precise cause
of rejection.
Business Impact:
Turn network failures into actionable intelligence — improving roaming QoS, optimizing
network selection, and keeping devices reliably connected worldwide. No guesswork, no bind
spots.
Designed to Scale Intelligence — Not Complexity
“What stands out about SIMbae is that it’s a contextual decision system. Every new feature expands what’s possible without increasing system complexity. The architecture allows high expression value — we can implement advanced orchestration logic efficiently, without layering on unnecessary overhead.”

Accelerate SIM Applet Innovation
Break the Java Card bottleneck - integrate existing applets functionality and deliver new SIM applet innovations in weeks, not months.
Traditional SIM development requires scarce Java Card expertise and takes months to deliver basic functionality. SIMbae changes the game entirely.
- Every SIMbae release is fully featured — similar to how Excel provides its complete toolset in every edition.
- No-code framework with drag-and-drop templates to create your unique applet
- Exponentially faster development cycles (weeks, not months)
- Empower existing teams - integrate in-house developed custom Java Card code and enable business and IT staff to easily create more capabilities
- Pre-built features that go beyond today's SIM applet capabilities
- Eliminate developer scarcity as a business constraint
Unlock the SIM's Potential
Move beyond basic connectivity to intelligent, value-added services.
Most SIMs provide authentication and basic connectivity. SIMbae™ transforms the SIM/eSIMinto an intelligent execution layer — enabling context-aware, deterministic network behavioracross public, private 4G/5G, Wi-Fi, satellite, and hybrid environments. Built on a state-machine architecture and leveraging established SIM Toolkit standards, SIMbaeunifies advanced SIM capabilities into a single programmable control layer — expanding functionality while maintaining low system complexity.
- Context-aware connectivity orchestration directly in the SIM
- Deterministic public/private/satellite network switching
- Direct visibility into network events across 2G to 5G
- Multi-IMSI management and dynamic subscription orchestration
- Intelligent roaming and PLMN steering
- Secure network attachment policies at the identity layer
- Quality-of-experience monitoring and validation with automatic reversion
- Automated edge decision-making independent of OS or cloud
- Embedded, non-overridable control inside the secure element
- OTA lifecycle management at global scale
- Enable new revenue streams and reduced operational costs

How SIMbae™ Works
Context Aware Orchestration
SIMbae leverages established SIM Toolkit standards and integrates multi-source contextual
awareness — including satellite positioning systems, Wi-Fi environment signals, and cellular
radio proximity metrics — into its SIM-based state engine.
Framework + Templates
Build smarter, faster. SIMbae™ delivers out-of-the-box SIM applet capabilities with a familiar, “Excel-like” experience for rapid prototyping. Pre-designed frameworks and a standardized code base accelerate development while increasing sophistication, with local logic that reduces cloud dependency and enables instant responses.
Super-Applet Architecture
Lifecycle Management
Secure Over-the-Air (OTA) updates keep SIMs current with latest features and security patches, minimizing operational costs and ensuring devices stay current.
