What are the different payment modes I can use to set up an AutoPay for my SIP? 

You can set-up an auto payment by using UPI, netbanking, or a debit card. 

Note: The netbanking or debit card option would only be visible if your SIP amount is greater than ₹ 15,000. Please  ensure that you have enough balance in your account before your SIP date.
