How to stop UPI?

To stop using UPI services, you can deactivate your UPI ID directly through your payment app settings by selecting the option to deregister or unlink your bank account. Alternatively, you can contact your bank's customer service to request a permanent block on UPI services linked to your account. For urgent situations like a lost phone, immediately block your SIM card and notify your bank to prevent unauthorized transactions. These steps ensure your financial details remain secure.
