How to increase credit limit on RBL Bank credit card?

I have been using my RBL Bank credit card for 24 months with a clean repayment history. How can I request a credit limit increase, and what factors does the bank consider?

Two cards from the same bank usually share credit limit, not stack it. So if bank gives you ₹2 lakh total, splitting between two cards doesn't increase your available credit. That's a common misconception people carry when applying for their second card.
