    SMS alerts vs Cell Broadcast

    Queued to subscriber lists, delivery inconsistent
    New: Cell Broadcast via local towers
    No phone number, no data plan, no app

    The old system pings individual numbers through telcos. CBS blasts a radio packet to every compatible phone in range, bypassing congestion.

    Three alert levels, two languages

    The ministry said alerts must clearly distinguish between general advisories, severe warnings and mandatory evacuations, delivered in Bahasa Melayu and English with local dialects where necessary.

    Who gets the test alert

    • Selected areas in Selangor
    • Selected areas in Kuala Lumpur
    • Flood-prone zones in Kelantan
    • Flood-prone zones in Pahang

    The 19 November broadcast targets phones in designated flood-prone zones across four states. If your phone is in one of these areas, expect a simulated siren.

    What changes for NADMA and telcos

    Current: NADMA + telcos push SMS
    Batch blast to subscriber lists
    Future: CBS via cell towers
    Area-targeted radio broadcast, no number needed

    Built for every phone

    • Vibrations and audio alerts
    • Screen reader support
    • Voice output for visual impairment
    • Local dialects where necessary

    The system includes features so users with visual, hearing or reading disabilities can still receive and understand emergency alerts.

    Bottom line

    One siren, one rule

    On 19 November, if your phone in Selangor, KL, Kelantan or Pahang blasts a disaster alert, it is a drill. The real system will send three levels of warning in Bahasa Melayu and English via local towers, no app needed.
