This network is very old when compared with all the networks. But all the networks improved. Actually my dad bought this sim. My dad’s point of view this is a very bad network. This completely worst. We are using bsnl broadband. Firstly it was very good. but now it is very very bad. All the time network going down. Atleast once in a week we experience this type of networks problems either it is bsnl network or bsnl broadband. So please don’t try to buy these. We are planning to take another netwok.
