MTNL Mumbai Plan change cost?

[Mr.cool]

Hi Everyone!

I am planning to change my broadband plan but not sure about the cost if i change it in middle of the month.
I did call 1500 regarding this and they only told that i will be charged as per new selected plan and data used before. I did asked them to share approximate cost but they told they can't.

I have used 15 GB of data till now. Can you anyone let me know the cost or on what basis i will get my this months bill?

There is no cost for changing your plan. If you change in the middle of the month then they apportion on pro rata basis
