Reliance is very bad network. Its signal is not good very flactuating. If you call someone the voice comes like you are in traffic jam , starting - stopping . You can see full stick of network in mobile, but if you go to make a call it starts its traffic jam. The Mobile data also very very bad. It takes lot time to load any page. Eeither 3G data or 2G data Reliance has Very bad performance. The promo packs, rate cutter, data packs are same as Idea, Vodafone, Airtel. Its best to use other network except Reliance.
