USE CASES / IOT RESILIENCE & FLEET ASSURANCE

When a device goes dark, the SIM can still act.

SIM-level monitoring and autonomous recovery keep unattended fleets connected — across networks, borders, and the failure modes firmware never anticipated.

// The problem

An offline device can't be fixed remotely — by definition.

Every IoT operator knows the loop: a device drops off, the platform shows "last seen 3 days ago", nobody knows if it’s the device, the network, or the SIM — and the answer is a truck roll. Static PLMN lists can’t adapt to local outages. Firmware-based recovery needs the OEM, a QA cycle, and devices that still have connectivity to receive the update. Data-only APNs and roaming edge cases silently strand fleets.

// Why SIM-native

The SIM is the only recovery agent already inside every device.

The applet doesn't need the cloud to act. It observes registration state, signal, and reachability locally, and executes pre-configured recovery logic — cycling networks, resetting forbidden-network lists, switching IMSI — until service returns. When connectivity is back, it reports what happened. No firmware dependency, no app, and it works identically across every device model in the fleet.

// THE OUTCOME

Higher fleet uptime, fewer truck rolls, faster root-cause analysis, and connectivity SLAs you can actually evidence — delivered by the one component you already ship in every device.
