This was a massive, bulky device weighing around 2.5 pounds (1.1 kg) with a battery life of about 20 minutes. The first commercially available mobile phone, the Motorola DynaTAC 8000X, was released in 1983. It was prohibitively expensive and primarily used by professionals and wealthy individuals.
- Second Generation (2G) Mobile Phones (1990s): The 1990s saw the introduction of second-generation (2G) mobile phones, which used digital networks, rather than analog. 2G networks offered clearer voice calls, and text messaging (SMS) became popular. Phones began to shrink in size and became more affordable for the general public. Nokia and Motorola were the dominant brands during this period.
- Third Generation (3G) Phones and Smartphones (2000s): In the early 2000s, 3G technology made it possible to access the internet via mobile phones. This led to the development of smartphones, with enhanced features such as web browsing, email, and video calls. Nokia's Symbian platform and BlackBerry were initially dominant, but Apple's release of the iPhone in 2007 and Google's Android platform (launched in 2008) transformed the industry.
- Fourth Generation (4G) and Beyond (2010s-present): 4G technology brought faster internet speeds and the ability to stream video and play online games with ease. As smartphones grew more powerful, they became essential tools for business, entertainment, and communication. The iPhone, along with devices running on Google's Android operating system, became the most popular models worldwide. Today, 5G is the latest technology, promising even faster speeds and more reliable connectivity.
