Public warning systems are full of misconceptions. At Intersec, we have spent years implementing these systems across the world, and we have repeatedly heard that they are "too expensive," "too complex," or "too intrusive." Every situation is different, every country brings its own constraints, and every deployment teaches us something new.

This series is our way of sharing that experience, and setting the record straight. One misconception at a time. Short, factual, and built for professionals working in emergency management, telecoms, and public safety.

    The loud alarm, the impossible-to-ignore buzz, that's real. But it only applies to one specific alert level. In this episode, we walk through the full Cell Broadcast level system, explain when silence is actually the recommended approach, and show why authorities have far more control over the citizen experience than most people assume.

  • Myth #9: Location-based SMS does not work for roamers

    Myth #9: Location-based SMS does not work for roamers
    Apr 29 2026

    If you're visiting a country when an emergency hits, will you get the alert? In this episode, we clear up a common misconception about roaming and location-based SMS, and explain how two different mechanisms, HLR Bypass for inbound visitors and passive location tracking for outbound travellers, mean operators can reach virtually everyone.
