SIM Verify

Manage the risk associated with SIM swap


Businesses are facing a steady increase in fraud related to the takeover of online service users' accounts.
To do this, fraudsters get the credentials of customers' mobile lines through phishing campaigns, then they usurp their identity and claim a new SIM card from their Dealer (SIM swap).

Fraudsters are given the opportunity to receive OTP codes, to authenticate themselves and make bank transactions or purchases, in place of the customer.

With SIM Verify, the service provider is informed that the SIM card has been activated recently and can thus:

  • Manage the risk of SIM swap fraud through reliable mobile operator information
  • Carry out a check in compliance with the rules resulting from the General Data Protection Regulation (GDPR)

How does it work ?

        The service provider, who wants to check whether the activation of the SIM card is

        recent or not, queries SFR for the mobile number concerned
