I went to BSNL office yesterday, they said that i will have to apply for a telephone connection first, and i will have to pay 500 Rs for that. Only then i can apply for Dataone connection. I will apply for 600 Rs Combo plan after that, that means that i will be paying 1100 Rs only. No installation charges, nothing additional besides this.And i was thinking that i will have to pay atleast 3000 Rs but instead i will be paying 1100 Rs only. I won't buy the router but i will get it on rent. Are there any additional hidden charges besides these ? And what is the monthly rental including taxes and router rental for Combo 600 plan.
