Maybe that's when the popular expression "the rich also cry" appeared? It was then that the idea of abolishing "telephone" slavery was born. It was necessary to give freedom to a person in a mobile network. This is how the Subscriber Identification Module appeared. In Russian, the module immediately acquired the feminine gender: sim-karta, also known as sim-ka or simply simka. The first SIM card was very similar to a credit card, which is easy to explain. Like any bank card, SIM is a type of Smart card and is a miniature computer. The SIM card includes the functionality of a processor, RAM, file system, and input-output controller.
The first mobile "bricks" easily accommodated finland email list the so-called full-size SIM card, but gradually phone manufacturers, improving technology, sought to make gadgets ever smaller. And so, since the beginning of the 21st century, the mini-SIM card has become widely used. This format is still doing quite well. world, a micro-SIM card appeared on the market in 2003. It was smaller than micro and, it seemed, couldn’t get any smaller.

Initially, they were planned to be used for communication between the card and the phone in the USB standard, but this approach did not find its grateful consumer.
