Take Out the Sim Card from your iPhone

The first fix that you need to act upon is to take out the sim card from your iPhone and properly insert it again. You never know, the SIM card error could have been caused by the SIM having slightly dislodged from its designated position. Grab your SIM ejection tool then gently insert the tool into the small pinhole opening next to the SIM port until the SIM tray pops out of the iPhone. Grab and pull out the SIM tray then follow through with cleaning both the tray and SIM card with a dry cotton cloth. After that, go ahead and properly place the SIM on its tray and reinsert the tray into the SIM port. At this point, the NO SIM CARD Installed Error should be fixed and the network bars should be popping up. If the error persists, proceed to the next fix.
