As the cellphone has evolved into the smartphone, the desire for Internet access on these devices has led to data networks being included as part of the mobile phone network. While Internet connections were technically available earlier, it was really with the release of the 3G networks in 2001 (2002 in the US) that smartphones and other cellular devices could access data from the Internet. This new capability drove the market for new and more powerful smartphones, such as the iPhone, introduced in 2007. In 2011, wireless carriers began offering 4G data speeds, giving the cellular networks the same speeds, that customers were accustomed to getting via their home connection. Beginning in 2019, some part of the world began seeing the implementation of 5G communication networks.

Some have speculated that the 5G implementation will lead households to eliminate the purchase of wired Internet connections for their homes, just using 5G wireless connections instead.
