Sonimis turns the SIM already inside every subscriber's device into a tamper-resistant identity vault and a continuously verifying MFA endpoint - one that keeps working even while the handset sits idle.
Sonimis doesn't add another app to trust. It activates the secure element that's already there, using the Applet layer and OTA channel operators already control - so identity assurance runs on the SIM's own clock, not the handset's attention span.
Credentials, keys, and identity attestations are provisioned into the SIM's tamper-resistant secure element under GlobalPlatform lifecycle management. They're issued, rotated, and revoked over the air - and never exposed to the handset's operating system or app layer.
The Applet speaks over SIM Toolkit and the OTA or built-in secured channel - independent of whatever app has focus, or whether the screen is even on. It can challenge, respond, and attest to presence on a schedule the network sets, not the user.
Through the Access Rule Applet-Master (ARA-M), Sonimis extends carrier-level privileges to specific handset applications - access to telephony functions and device identity normally reserved for system software - without needing physical access to the SIM.
The identity server initiates a challenge over the secured channel, on its own cadence.
The challenge rouses the Applet directly - no host app, no user interaction required.
The vaulted key signs a response, binding subscriber identity to that specific secure element.
The network refreshes a live presence score - continuously, whether the device is active or idle.
Sonimis licenses the Applet and the identity platform behind it to operators and government programmes. Get in touch to talk about your deployment.
