The issue is your SIM card<\/h3>\n\n\n<p>Your SIM card could be either dirty or damaged. If you suspect it might be dirty, try the following:&nbsp;<\/p>\n\n\n\n<ul>\n<li>Take out the SIM card and gently rub the golden chip with a rubber eraser or a cotton swab. For a more professional approach, get a Gold Guard pen at your local electronics store and gently clean the SIM card with it.&nbsp;<\/li>\n\n\n\n<li>If cleaning it doesn&rsquo;t work, your SIM card might be damaged. Inspect the SIM card under light and look for scratches, cracks or signs of damage on the surface of the card.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>SIM cards get slightly damaged each time they are inserted in and out of a device. Over time, the friction associated with the motion can scratch and damage the chip<s>. <\/s>The greater the wear on the chip, the more likely the card will become faulty.&nbsp;<\/p>\n\n\n\n<p>Also check out <a rel=\"noreferrer noopener\" href=\"https:\/\/mobilepains.com\/how-do-i-know-if-my-sim-card-is-bad-symptoms-causes-fixes\/\" target=\"_blank\">how do I know if my SIM card is bad?<\/a> for more about SIM card issues.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"2-the-issue-is-your-sim-card-readernbsp\">2.
