  • An OTP will be sent to the registered mobile phone number
  • Enter your OTP and click “Submit” to continue
  • Next, the linked 12-digit Aadhaar number had to be entered
  • The telecom operator would then send a message for OTP generation.
  • Now, you will be required to submit your KYC details, OTP and accept all the terms & conditions
  • A confirmation message regarding Aadhaar and phone number re-verification will be sent after the completion of the process
