  description: >-
    The SIM Swap API enables applications to check whether a SIM swap occurred
    recently on a mobile number. SIM swap fraud is a common attack where
    criminals take over a victim's phone number to bypass SMS-based 2FA.
    Based on CAMARA open standards. Available in Spain, Germany, Brazil,
    and the United Kingdom through the Telefónica Open Gateway.
