Why is my UPI PIN not setting?

Your UPI PIN might not be setting due to incorrect debit card details, an expired card, or a mobile number mismatch with your bank records. Ensure you have a stable internet connection for OTP verification and that your SIM is inserted in the primary slot. Other reasons include bank server downtime or exceeding the daily limit for PIN change attempts. If the issue persists, verify your details with your bank or try again after 24 hours if your account is temporarily locked.
