Unlike other mobile operators Vodafone has also the the good and bad points. Firstly in my locality the network coverage is strong but it may vary to other places. The 4G speed is high enough to make the work faster. But to me the main problem is that it cuts unnecessary bills from the account repeatedly. Another biggest problem is that its very costly in case of data plans & there is no unlimited data plans. Also the excess data charges are high. The normal plans are higher than other operators. 4G coverage is about 65 percent.
