If you are using any Ecommerce platform, go with cobranded cards like AMAZON PAY ICICI CARD or FLIPKART AXIS CARD.
If you don't have a credit history, then first build that with the help of EMI's or BUY NOW PAY LATER like AMAZON PAY LATER.
For any bank to give you unsecured card they will first check your credit score then your credit history to know whether you are financially stable and wise and making repayments on time or not.
SO, TRY TO BUILD HISTORY FIRST.
