Moreover its unethical to change the plan midway
Mine is forever stuck on 2.05kb left.I finished my data quota of 2 GB in half an hour then within 5 minutes I got a message that the JPO is activated then messages stating each JIO name got activated. So first finish your data to Zero , then you will get a message saying that request accepted and UL pack will be activated. @AbhishekMSharma
