My friend has Flipkart paylater since one year. She hasn't used it even once and still got three LE so far. Initial limit was 500, then 30k and recently again increased to 80k. No other loan or CC.
Meanwhile I had 500 limit for more than a year and was increased to 3k only after using for many times. I have closed it in Nov 2022 after getting my first unsecured CC in September.
