The evolution of cell phones

Cell phones have evolved significantly since their invention. At first, they were big, heavy devices that only allowed you to make phone calls.

Over time, new features were added, such as sending text messages, cameras, internet access, applications, and much more. 

The first cell phones were analog, but over the years, more advanced technologies have emerged, such as GSM, CDMA, and 3G. 

With 4G, the connection speed has increased considerably, allowing for faster internet browsing.
