You should receive your One-Time Password (OTP) code on your phone shortly after submitting your mobile number. Make sure you have entered your mobile number correctly. If you have not received the OTP code after waiting for more than a minute, you can request a new OTP code using the 'resend' button that appears on the verification screen. If you are still unsuccessful after several attempts, wait for an hour and try again.
Important: If your registered phone number is no longer active, it is not possible to update it, as the system does not support phone number changes. We are working on adding this feature in the future.
