Why is my UPI verification not working?

UPI verification often fails due to mobile number mismatch—the SIM number must be the same as the one registered with your bank account. Other common causes include poor network signal, an inactive SIM card, or the UPI application lacking necessary permissions to read SMS. To fix this, ensure your SIM is active, check your network, and grant the app all required permissions. If using a dual SIM phone, ensure the correct number is in the primary slot.
