The abbreviations 2G, 3G and 4G refer to the different mobile phone standards. 

The difference between 2G, 3G and 4G lies mainly in the speed of data transmission. This is important on mobile devices such as smartphones to surf the Internet as fast as possible. 

Currently, 2G, 3G and 4G exist in Germany, but not all three types are represented in every region. A smartphone always chooses the best possible network, but not every smartphone supports 2G, 3G and 4G. In addition, many mobile phone providers currently offer a 4G connection only with certain contracts.
