Critical alerts shouldn't be metered

When a server goes down at 3am, you want a text — not an email that sleeps in an inbox. But per-message SMS pricing makes teams ration alerts.

SimGate sends alerts from your own SIM at a flat monthly price, so you can be generous with the alerts that matter and keep cost predictable.

Frequently asked questions

Can my monitoring tool call SimGate directly?

If it can POST JSON to a webhook with custom headers, yes. Tools like Uptime Kuma and Grafana support this, and automation platforms like n8n make it a drag-and-drop step.

How fast are alerts delivered?

Sends are dispatched to your connected phone immediately; delivery then depends on your mobile network, usually within seconds.
