Mobile technology is the technology used for cellular communication. Mobile code-division multiple access (CDMA) technology has evolved rapidly over the past few years.

Many types of mobile operating systems (OS) are available for smartphones, including Android, BlackBerry OS, webOS, iOS, Symbian, Windows Mobile Professional (touch screen), Windows Mobile Standard (non-touch screen), and Bada. The most popular are the Apple iPhone, and the newest: Android. Android, a mobile OS developed by Google, is the first completely open-source mobile OS, meaning that it is free to any cell phone mobile network.

Since 2008 customizable OSs allow the user to download apps like games, GPS, utilities, and other tools. Users can also create their own apps and publish them, e.g. to Apple's App Store. The Palm Pre using webOS has functionality over the Internet and can support Internet-based programming languages such as Cascading Style Sheets (CSS), HTML, and JavaScript. The Research In Motion (RIM) BlackBerry is a smartphone with a multimedia player and third-party software installation. The Windows Mobile Professional Smartphones (Pocket PC or Windows Mobile PDA) are like personal digital assistants (PDA) and have touchscreen abilities. The Windows Mobile Standard does not have a touch screen but uses a trackball, touchpad, or rockers.
