  title: Account-takeover check for a Brazilian mobile line
  version: 1.0.0
  description: >-
    Before trusting a phone number as an authentication factor, ask Claro Brasil
    two questions: has the SIM pairing changed recently, and where is the device
    on the network? Step one is the decision gate — if the SIM was swapped inside
    the window, stop and escalate rather than spending a location lookup on a
    line you already distrust.
