Certainly, the inevitable device these last years is the mobile phone. Its evolution, through the smartphone, has made it equivalent to some computers.
From its basic feature, that is to allow people to communicate, it has become much more, combining the PDA to a personal computer. It is now present everywhere, as long as the network operator is available.
Basic features of a mobile phone
All cellular phones have at least one feature in common: the possibility to call someone and be called. Through a radio link with a network operator, the communication is made possible. The SMS has not always been around on cellular phones, but is now a common, and one of the mostly used features of these famous devices.
Internet made possible on a mobile phone?
The evolution of technology has been really fast paced these last decades. The cellular phone is basically like a computer. It can even access the internet through network operator services like WAP or 3G, as long as the device is in a coverage zone. Among these two types of services, 3G offers an experience much more similar to the one obtained by Wi-Fi. The WAP connection is much more limited.
Obtaining applications and making payments with a mobile phone
Mobile phone creators are realist when it comes to the performance and limits of smartphones. They are not trying to compete with computers, at least not always, but are focused on creating devices that complement the computer. This means that actions, softwares or services that were restricted to computers are now extended and available on mobile phones. Another example of how mobile devices are more and more present in our lives is the fact that they can be used to make payments. E-wallets and contactless payment are becoming really popular.
