Hi everyone! I'm from Bellary(Karnataka).. Currently I'm using BSNL broadband 500C+ plan(2.5GB usage, night 2-8 unlimited and 50 free calls).But from the past 2 months or so, I get the feeling that 2.5GB is insufficient.. So I'm planning to migrate to either 750UL or 750 Combo UL plan..Actually we normally won't use landline for making calls. So at the end of the month we usually get Rs.664 as our bill..So my questions are as follows,1) How much can I expect first month's bill, if I switch to 750UL??2) How much can I expect first month's bill, if I switch to 750 Combo UL??3) How much can I expect the bill from second month onwards??4) What if I avail 20% discount on the bill? Then how much should I pay??Please remember WE DO NOT USE LANDLINE FOR MAKING CALLS because we all have mobile phones..I'm really confused! Please help me out.. Thanks in advance..
