Currently, a typical subscriber identity module can come with these sizes:<\/p>\n<ol>\n<li><strong>Nano-format (4FF): <\/strong>thin chips used in most modern devices;<\/li>\n<li><strong>Micro SIMs (3FF): <\/strong>these cards for iOS gadgets from 4 and up;<\/li>\n<li><strong>Mini sim cards (2FF): <\/strong>a physical chip of large format;<\/li>\n<li><strong>Full-size module (1FF): <\/strong>this type (from the past) has the size of a typical bank card.<\/li>\n<\/ol>\n<p>By purchasing a SIM today, the user receives a chip mounted on a universal piece of plastic that meets all established standards. Whatever form the SIM card has, they all have one thing in common \u2013 these are real IT-devices in miniature. A small module with six or eight contacts has almost the same components as a conventional system unit.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-391 size-large\" src=\"https:\/\/esim-man.com\/wp-content\/uploads\/2023\/03\/guest-posts-logo-93-1024x576.png\" alt=\"SIM card sizes\" width=\"1024\" height=\"576\" srcset=\"https:\/\/esim-man.com\/blog\/wp-content\/uploads\/2023\/03\/guest-posts-logo-93-1024x576.png 1024w, https:\/\/esim-man.com\/blog\/wp-content\/uploads\/2023\/03\/guest-posts-logo-93-300x169.png 300w, https:\/\/esim-man.com\/blog\/wp-content\/uploads\/2023\/03\/guest-posts-logo-93-768x432.png 768w, https:\/\/esim-man.com\/blog\/wp-content\/uploads\/2023\/03\/guest-posts-logo-93.png 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p><strong>So, a regular SIM card has these features:<\/strong><\/p>\n<ul>\n<li>Random access memory (<a href=\"https:\/\/www.techtarget.com\/searchstorage\/definition\/RAM-random-access-memory\">RAM<\/a>);<\/li>\n<li>Processor (<a href=\"https:\/\/en.wikipedia.org\/wiki\/Central_processing_unit\">CPU<\/a>);<\/li>\n<li>Permanent memory (ROM);<\/li>\n<li>The file system;<\/li>\n<li>I\/O controller.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"the_most_common_problems_with_sim_cards\"><\/span>The most common problems with SIM cards<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A physical format SIM card can fail, just like any other electronics. Here are the most common sim card problems causes:<\/p>\n<ul>\n<li><strong>Mechanical damage. <\/strong>There are many potential reasons. This can be an ordinary replacement of a card inside the device or damage to individual contacts and elementary cracks. The chip contacts often wear out due to frequent manipulations (changing the subscriber identity module, etc.);<\/li>\n<li><strong style=\"font-size: 16px;\">Corrosion or contamination. <\/strong><span style=\"font-size: 16px;\">Internal metal grooves can oxidize in the motherboards of a smartphone or tablet. When the user changes a SIM card, he touches its contacts. This can cause problems with sim card like corrosion or contamination;<\/span><\/li>\n<li><strong style=\"font-size: 16px;\">Limited lifespan. <\/strong><span style=\"font-size: 16px;\">The resource of mobile chips has a service life. Be prepared; you must change a phone card in a few years when it finally exhausts itself;<\/span><\/li>\n<li><strong style=\"font-size: 16px;\">Static electricity. <\/strong><span style=\"font-size: 16px;\">This module may break due to static electricity discharge. Such an issue does not happen as often as the previous two, but it is likely.<\/span><\/li>\n<\/ul>\n<p>Moreover, SMS and numbers contained on a particular module cannot be restored. The number will simply be transferred to a new SIM.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"ways_to_fix_sim_card_problems\"><\/span>Ways to fix SIM card problems<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Let&#8217;s figure out what are sim cards used for and what can be done to solve common issues:<\/p>\n<ul>\n<li><strong>Checking the receiver contacts.<\/strong> There is a possibility that physical cards are of decent quality; the damage to the device socket itself is the crucial reason for failure. Contacts could be bent due to careless application. You can try to fix it by yourself. For this, turn the antennae in the SIM card tray. In modern gadgets, side loading is used, and sockets are built into multilayer boards for SIMs;<\/li>\n<li><strong>Use another device.<\/strong> <span style=\"font-size: 16px;\">Such an elementary check will determine any causes of the sim card problems. Just swap SIM cards with a different phone and decide which gadget works;<\/span><\/li>\n<li><strong>Cleaning of internal contacts.<\/strong> Minor oxides and impurities are cleaned elementarily with an ordinary stationery eraser. It can remove dirt or surface membranes quickly;<\/li>\n<li><strong>Choose eSIM.<\/strong> <span style=\"font-size: 16px;\">This is top solution, and here is why.<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"benefits_of_esim\"><\/span>Benefits of eSIM<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Cost reduction is crucial for almost any mobile operator. The replacement of plastic after each breakdown of the physical SIM card brings extra costs to cell phone companies. That is why you should choose an embedded SIM if you know well what are sim cards used for. So, here are pros of switching to eSIM:<\/p>\n<ol>\n<li>Switching to an eSIM card allows you to save valuable storage space;<\/li>\n<li>Virtual mobile chips are impossible to lose;<\/li>\n<li>With eSIM, you don&#8217;t need to go to a telecom spot to pick a tariff. One can do this remotely online;<\/li>\n<li>One chip for several mobile devices;<\/li>\n<li>High-security status. You can read about how safe it is to use eSIM <a href=\"https:\/\/esim-man.com\/is-esim-safe-everything-you-need-to-know\/\">here<\/a>.<\/li>\n<\/ol>\n<h2><span class=\"ez-toc-section\" id=\"summary\"><\/span>Summary<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Transition to an embedded card is justified, and many have already appreciated all benefits of eSIM. You download virtual electronic cards from the operator and then activate it on any of your devices. Chips have many advantages, such as increased security and fast activation. In case of theft or loss of gadgets, you will find it more likely, as it is much more challenging to remove an eSIM than physical mobile chips. Besides, you can use an electronic format card on other devices without a sim card issue. For example, connecting your laptop to eSIM will use a data package from your cell phone without creating an additional Wi-Fi hotspot.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Have you ever had such a thing &#8211; just bought a new smartphone, inserted a SIM card, and, in a few days you faced a question &#8211; why isn&#8217;t my sim card working?
