GkQuizAnswers explains mobile phones
Mobile phones, as mentioned, were used only for making and receiving calls, and they were so large that it was impossible to carry them in one's pocket. These phones used primitive RFID and wireless systems to transmit signals from a cabled PSTN endpoint.
Later, mobile phones within the Global System for Mobile Communications (GSM) network are able to send and receive text messages. As these devices have evolved, more features have been added, such as the Multimedia Messaging Service (MMS), which allows users to send and receive pictures.
Most of these MMS-enabled devices are equipped with cameras, which allow users to take pictures, add captions and send them to friends and relatives who also have MMS-enabled phones.
In addition to texting and camera features, cell phones began to be created with limited ability to access the Internet, known as "data services". The oldest phone browsers were proprietary and only allowed access to a small subsection of the Internet, which allowed users to access items such as weather, news and sports updates.
Eventually, phone makers began to engineer these phones to access the entire Internet, and webmasters, government offices, and other domain holders for all types of businesses began to respond to web sites for access by mobile phones.
This trend called "Responsive Design" has changed the world of the Internet, with mobile phone transactions making up a large part of e-commerce sales and other activities.
