I am using this sim 6 year ago.At that time company provide the lot of offer. the internet pack and calling is very cheaper. but if we talk about today situation the call rate is very expansive also net pack. the company don’t provide affordable offer.today situation the company take a charge 1 rupees per mint that’s very costly. I recommended to the company please cheap the call rate and internet pack.
