  3. Is this 120GB data for 180 days or 60 days? Because if a subscriber doesn’t include utilities entirely the 2GB data per day, then those data will be carried over till 180th day from the recharge. Am I right?

  5. It looks like the actual validity of free calling and data is only for two2 months. Is it possible to increase efficacy and decrease the free 3G data and calling option on the same price?
