If you don't receive the OTP on your phone number, please check the following-
1. Check whether the Phone number you have entered is correct.
2. Make sure you have active recharge and a stable internet connection.
3. Due to a low network, you might not receive OTP. Kindly wait for some time and try generating OTP again.
4. You may also restart your phone and regenerate OTP again.
5. If you've already installed Truecaller on your phone, you can also try logging in using it.
Alternatively, you can also try voice OTP, where a call will be received on your phone number to provide you with the OTP.
If you still facing the same issue, we request you to create a ticket at [email protected] or you can also talk to a Live agent (Menu > Help).
