There are many credit cards you can try.
I am only suggesting life time free cards here.
1) Amazon Pay ICICI: Best LTF Card, Less chances of approval, no UPI support only VISA. Good rewards.
2) Jupiter CSB: Nowadays it's getting approved for everyone. It's a Rupay UPI Credit Card. Less rewards.
3) HDFC Millennia: Try applying HDFC Millennia offline. They offer it for lifetime free if applied through offline. Available on RUPAY as well. Decent rewards.
4) Axis Neo: Now available for LTF. Approval chances are confusing. Less rewards.
