Bajaj Finserv EMI card allows you to make purchases for the pre-approved loan amount and make the repayment later in monthly instalments. The credit limit on the card is increased on review, and the approval is done on a quarterly basis. 

It is best to contact their customer care and request for an increase in the credit limit. If you have a good repayment record and credit behaviour, you have higher chances of getting your credit limit increased.
