Why integrate tru.ID for SIM swap monitoring
An important addition to your security stack
SIMCheck can be integrated alongside your existing 2FA solution to help protect user accounts on mobile.
Prevention is better than troubleshooting
SIM swap fraud is best prevented at source rather than dealt with after it happens to a user.
Step-up security challenges made easy
No SIM change? No problem. But, if the SIM shows as brand new, you can implement extra checks to verify account access.
Easy to deploy
tru.ID is an API platform with all the documentation and SDKs you need to integrate quickly and easily.
What makes tru.ID SIMCheck different
A new way to check mobile possession
Unlike SMS that only checks possession of a mobile number, tru.ID SIMCheck takes you to the source: the network-issued SIM card.
Silent security at each login
In-app SIM checks are invisible to the end user, and it's only when there's a new SIM that the user experience needs to respond.
Filter out potential fraudulent activity
You have deterministic proof that the mobile number is associated with a real network-issued SIM.
