Idea network is my first network and I havenot changed till now due to the offers from idea. The signal is alround and we neednit worry of signal. At present I am using RC 346 which gives 1gb daily and unlimited local + std for 28 days. The fulltalktime offers, rate cutters, are awesome. People like to change from one sim to another for the offers but the frequency in changing from idea to the other will be definitely low.
