Hi friends I am using idea sim since last 4 years and I am really happy with this sim.idea has very good network coverage where ever I have gone like in very small villages as well.idea 4g 3g speed is awsome , rates of internet pack and calls are high, compared too other networks.but still I will recommend you to use idea sim as it works really good.whereever you go you will find range.now there are some combo packs also introduced for validity of 28 in range near about 350 .though prices are high still worthwhile.
