SIM Swap Detection

Detect unauthorized SIM swaps before account takeovers occur
Taking over a user account through unauthorized SIM card exchange (SIM swap fraud) is one of the most dangerous and severe types of financial crimes in mobile channels.
The attacker, using social engineering or falsified documents, obtains a duplicate SIM card from the operator. From that point on, all one-time SMS codes, authorization calls, and notifications are sent directly to the fraudster's device. In this scenario, the traditional OTP code ceases to protect your customer and becomes a tool in the hands of the criminal. Our SIM Swap Detection service provides effective protection for users against phone number hijacking. It supports login security, authorization processes, and advanced identity verification systems, acting directly at the source of the threat.

What do you gain?

Preemptive identity theft protection

You gain the ability to detect the fact that a new SIM card has been issued before a criminal manages to carry out an unauthorized financial transaction, change access passwords or log in to the customer profile.
Precise signal for your decision-making systems
The solution is based on direct, authentic signals from the core networks of mobile operators such as Orange, Play, and T-Mobile. We completely dispense with uncertain heuristic analyses or guesswork.
Verification based on hard network data
The solution is based on direct, authentic signals from the core networks of mobile operators such as Orange, Play, and T-Mobile. We completely dispense with uncertain heuristic analyses or guesswork.
Perfect user experience without unnecessary friction (Zero Friction)
The entire verification process runs completely unnoticed in the background. Legitimate users don't need to perform any additional steps, enter passwords, or click on notifications, ensuring the highest conversion rates.
How does it work?
The integration is based on a modern, ultra-efficient REST API (HTTPS encrypted communication, secure API key authentication), which returns responses from the network in milliseconds. The service operates based on the official, global GSMA Open Gateway standard, providing a single, centralized access point to the systems of all key operators in Poland via NEXT MOBILE. The system queries the operator's database in real time for the exact date and time of the last SIM card registration on the network, allowing for immediate detection of anomalies just before a sensitive transaction is approved.
