SIM Binding API is an effective security solution that links a user’s digital identity with the SIM inserted in their mobile device. It ensures that only the device with the registered SIM is accessing the app used during the onboarding. If the SIM is removed, replaced, deactivated, or inserted into another device, access will be blocked until the SIM is reverified.

How does the SIM Binding Work?

• User Registers on the App: The system verifies the user’s mobile number and links the account to the SIM used during onboarding.
• SIM Verification on Each Login: Whenever the user signs into the system, the system will check the presence of a SIM in the device.
• Device and SIM Match: Access is granted only when the SIM device matches the registered combinations.
• Blocks Unauthorized Access: If the SIM is removed, swapped, or cloned. The login or transaction request is immediately denied.

Use Cases

• Banking and Fintech Apps: SIM Binding API adds security to the financial apps. It ensures that only the customer-registered SIM can access the app. It helps block SIM Swap attacks, fraudulent logins, unauthorized transactions, and account takeover.
• UPI and Digital Payment Wallets: SIM binding helps prevent unauthorized access to wallets and reduces payment-related fraud.
• Insurance, Trading, and High Risk Digital Platforms: SIM binding helps verify genuine users, prevent identity manipulation, and transaction fraud.
