Roaming charges for data pack and talktime on Idea postpaid sim?

Hi, i am going to travel from lucknow to pune and while travelling through trains there will be lots of states come in between. I want to know that currently i am using idea sim on postpaid connections and i dont know the roaming charges of data pack talktime for my prepaid sim.

Could anyone suggest me what are the charges idea will cut on talktime and on data pack.

Rohitaz345, there is no roaming charges on data usage. Roaming charges are applied on SMSes and calls only. I have travelled across telecom circles and have kept my mobile internet on, there has never been any additional charges on data usage. Only that connectivity is a issue at times.
