Why am I not able to set a UPI PIN?

You may be unable to set a UPI PIN due to incorrect debit card details, such as the last six digits or expiry date. Other common reasons include using a mobile number not registered with your bank, poor network connectivity, or temporary bank server downtime. If you have exceeded the permitted number of attempts, your account may be blocked for 24 hours. Additionally, ensure your bank supports UPI and that you are using the latest version of the app for successful verification via OTP.
