I live at a place which is isolated from the city and no other operators signals are available here.
In dehradun I wasnt able to get signals of any other but idea was working very good. Although the speed of Internet was not coming good but network for calls was available.
One thing that I dont like about idea is that they give really good offers at the starting time when we buy sim but later on there are hardly any offers. Idea pls give more offers.
