Debit card problems in India

Adding a debit card could be very troublesome it seems. I've obtained a UCO Financial institution Debit Card (Visa). I have worldwide transactions allow too, simply in case. I'm making an attempt to Buy with INR. I add card whereas purchasing. I even get otp from UCO Financial institution. I set off the tx. Then binance exhibits error. 1. What does this error imply? 2. How do I truly buy with a debit card in any respect? I really need to use my bank card to buy. The P2P rates for USDT to INR is an absolute joke, getting fleeced by about 11% just isn't my favorite. Please advise.
