The part everyone else skipped

Not just data. Voice.

Streams of data pour in from every device. They converge, get organised, and on the same eSIM we carry a real, regulated voice line, the hard part nobody else builds.

Voice over eSIM and the PSTN switch-off →
Voice + data, one eSIM

Telecare & alarms

Keep emergency call paths alive as the PSTN is switched off in 2027, with no truck roll or copper.

Lifts & emergency lines

Compliant voice for lift autodiallers and safety lines, provisioned remotely over eSIM.

Multi-carrier by design

Voice routed across carriers from day one, with resilience built in and no single point of failure.

The platform, live

Run it before you commit.

Spin up lines on a free sandbox and run simsonic next to your current provider. Prove coverage, cost and activation on your own terms, then scale the exact same setup to a hundred thousand lines, across every vertical and every border.

Test

Run it in parallel

Provision lines on a $0 sandbox and run them alongside your existing provider. No carrier contracts, no hardware swap, no risk to production.

Validate

Prove it on your terms

Compare coverage, cost per line and activation speed against what you run today, across asset tracking, telematics, metering, EV, whatever you connect.

Scale

Expand with confidence

When you are ready, the same line, console and API run at 100,000+ lines across 190+ countries. No admin overhead, no bill shocks, just larger volumes.

Control your connectivity

All systems operational
One console for every line you sell or deploy, each carrying a Hyper ID it can prove.

This is the part no commodity connectivity console can show. Every line ships with a Hyper ID, a cryptographic identity the device can prove to your stack, not just a SIM number. Bind it to a device, attest its location, rotate it on a schedule. Identity is the layer, connectivity is just the transport.
