3G stands for ‘Third Generation Network’. Similarly, 4G stands for ‘Fourth Generation Network’. Both 3G and 4G networks enable you to access mobile data, however the speed of the Internet connection is the differentiating factor between the two networks. 4G networks provide higher Internet speeds when compared to a 3G network. The difference between these two networks does not affect your mobile data consumption. However, due to the higher speeds offered by a 4G network, you are more likely to engage in increased online activity, which directly impacts the amount of mobile data consumed.
