In my opinion Uninor(Telenor) new name which has a worst service provider ever.its the cheapest networks provider but does not have a singel step facility. Its signal strength is too poor.It covrages flactuates mostly at a time.mostly it does not have a covarage many times.Showing Emergency calls only.And the biggest Worst thing of this provider is Advertisements If we call the telenor customer its Advertisements make a big problem while calling and mainly call drops after 1Hr continous talking.i Dont like this service provider.And I also not recommend you to use this.And For Internet Dont Try This ever It will give you maximun 15-20kbps hardly in 2G connection.
