Operators own the network. They don't own the device, the OS, or the apps.
Once a device ships or a subscriber roams, most of what happens to connectivity becomes invisible. Network probes see the network's side of the story. Device apps depend on OS permissions, user installs, and battery budgets — and don't exist at all on feature phones or headless IoT devices. Firmware changes take quarters, not days.
There is one component that is present in every cellular device, runs operator-controlled software, and survives every OS update: the SIM.
SimX makes the SIM programmable, observable, and actionable.
SimX is a Java Card applet suite for SIMs and eSIMs plus a server-side platform and APIs. Deployed at manufacture or over the air, it works across device classes — smartphones, feature phones, routers, modules, and IoT — with no app, no OS dependency, and no changes to your network core.
Sense
Observe service state, signal quality, network events, cell context, and device changes from inside the SIM — even while roaming or offline.
Decide
Apply policy logic in near real time: server-decided rules for consistency and auditability, or SIM-resident logic for autonomous action when connectivity is down.
Act
Switch IMSIs, steer network selection, update SIM files, lock or unlock service, and trigger recovery flows — directly at the SIM layer.
Expose APIs
Feed events, telemetry, and controls into your OSS/BSS, analytics, CRM, or customer-facing products through REST APIs, webhooks, and Kafka streams.
One SIM-native platform. Multiple high-value use cases.
Built for the teams that own connectivity.
For Operators
MNOs, MVNOs, and global connectivity providers: device-side visibility your network tools can't capture, and SIM-level control your OTA platform can't deliver.
For OEMs
Automotive and connected-device programs: monitor, steer, and recover connectivity in products after they ship — without firmware cycles or app dependencies.
For OEMs →For Regulators & Public Sector
Independent, device-side evidence of coverage and quality of service, measured from real subscribers' SIMs at national scale — without drive-test fleets or operator-reported data.
For regulators →"Embedding intelligence directly into the SIM transforms what an MVNO can deliver. We’re now able to provide our users with the best available network anywhere in the country — automatically and without relying on apps or device behavior. It’s a huge leap forward in reliability and user experience."
"Working with Telkoa has brought our technology stack in our SIM-based services area to a completely new level with their existing services and the long-term value in the co-creation of more services tailored to the versatile world of IoT."
Pilot on the SIMs you already have.
No rip-and-replace, no firmware programs, no network core changes. A SimX engagement is designed to make the cost of finding out small and fixed.
Scope
We start from the problem — roaming cost, fleet downtime, QoE blind spots, fraud — and map it to the SimX modules that solve it: one, or a combination. You leave with a pilot design and agreed success criteria.
Pilot
The applet goes onto a controlled batch of your SIMs — or scan a QR and be live on an eSIM we provide the same day. Platform instance stood up; first KPIs from your own devices within days of activation.
Production
Staged rollout across the estate, integration with your OSS/BSS and analytics, and hosting on your terms — our cloud, your cloud, or on-premise.
Pilots are fixed-scope with agreed success criteria — you'll know if it solves your problem in weeks, not quarters.
Built for network APIs and AI.
SimX is API-first today — REST, webhooks, and Kafka expose SIM-level telemetry and controls to your own stack. And the SIM-native data SimX produces (location with confidence, device and identity signals, quality metrics) maps directly onto the capabilities the industry is standardising as network APIs. As operators build API businesses, SimX is designed to be the device-side source feeding them.
Continuous, OS-independent, per-SIM telemetry in standardised schemas — exactly the data layer AI and analytics need — plus a control loop that can act on what models decide. Anomaly detection and predictive steering are on the SimX roadmap; the data asset starts accruing from day one.
