I have Almost all service Provider Sim like Vodafone, Airtel, Reliance, Docomo and idea. but I like most idea because of its Good Internet Service in both 2G And 3G Platform. Also Providing High Speed. Call Quality is Also so good.
There are not getting any Technical error during Call. Sms Delivery Rate Is also so good. but one this which I didn't like in it is its Highly Call Rate 1.6 Paisa Per Minute. Some packs are available for Rate cutter But they are also very Costly Otherwise I think Good Network. in Both Cities and village areas.
