I read somewhere that with 2G connection we can save Internet data. But I wonder how it is possible as we are downloading the same quantity of data and what is different is the time taken to download it. 4G is the faster when compared to 3G and 2G is the slowest in the lot. If we use 2G we have to spend more time on net to download data but there is no change in the volume of data. I am curious to know if 2G in any way helps to save money on Internet?
