  description: >-
    SIM Swap Notification Subscription enables subscription to notifications
    related to SIM Swap events, reporting a change in the SIM card associated
    with a mobile phone number. A SIM Swap event often responds to legitimate
    device upgrades or replacements but is also susceptible to abuse through
    fraudulent activities.
