It is known as 4FF, which stands for &#8220;Fourth Form Factor&#8221; in technical terms. This designates it as the fourth stage in the development of SIM cards.<\/p>\n\n\n\n<p>More facts about nano SIMs are revealed below.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Nano_SIM_Size_and_Dimension\"><\/span>Nano SIM Size and Dimension<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The nano card was first introduced in 2012 to address the demand for progressively smaller components.<\/p>\n\n\n\n<p>A conventional SIM card is around 25 x 15 millimeters, and a micro SIM measures about 15 x 12 millimeters, while a tiny nano SIM measures just<strong> 12.3 x 8.8 x 0.67 millimeters<\/strong>.<\/p>\n\n\n\n<p>This means that it is substantially smaller than previous models. The smaller surface area frees up room in devices for additional technological components.<\/p>\n\n\n\n<p>Also, this SIM card only has an extra insulating card and a gold contact area to help avoid electrical shorts.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Advantages_of_Nano_SIM\"><\/span>Advantages of Nano SIM<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Wonder whether all phones use nano SIM now?
