Carrier Network Authentication
Authentication relies on carrier network infrastructure to validate mobile identities, offering a more stable and reliable alternative to traditional verification methods.

Users enter their mobile phone number in the app and initiate a login or verification request.

The system initiates authentication through the carrier network in the background to verify the consistency between the mobile number and the SIM identity.

After verification succeeds, login or identity confirmation is completed automatically. No SMS code is required, and the entire process usually takes only a few seconds.


User identity is verified through the carrier network without sending or entering SMS codes, reducing verification failures caused by SMS delays or interception.
Verification is handled through carrier network validation, eliminating the need to access device-level data such as installed apps or location information while maintaining strong security standards.
Users simply provide their mobile number to initiate verification. The process runs silently in the background and completes without interrupting the user journey.
