Solution No.1: Toggle Airplane Mode

Let’s start with the most basic option. If you’ve ever had difficulties with your iPhone’s Wi-Fi, cellular data, GPS, or Bluetooth, you know that turning on Airplane mode may solve the problem. If your iPhone indicates No Sim, try this easy method. Go to the Settings menu and choose Airplane mode. Allow 15-20 seconds for it to warm up before turning it off.

Solution No.2: Reboot Your IPhone

When was the last time you restarted your computer or smartphone? You’re probably aware that phones may behave oddly at times. Even if the SIM card is in the tray, your iPhone says No Sim Card. It indicates that your device isn’t detecting the card for whatever reason. The issue may be resolved with a simple restart. Press and hold the sleep/wake button until the slider appears, then move it. To turn your phone back on after it has been turned off, press and hold the sleep/wake button.

Solution No.3: See If Your SIM Card Is Properly Placed

The SIM card may shift slightly from time to time. Reinserting the SIM card, even if it didn’t move, is something you should absolutely do. Remove the SIM card from your iPhone and turn it off. Wipe away any dust that has accumulated in the tray or on the card. Make sure the SIM card is in good condition. If that’s the case, your iPhone will display “no SIM card installed” and you’ll need to contact your carrier to get a new SIM card. Is there any harm to the card? Replace it with the one in the tray and power up your phone.

Solution No.4: Try Another SIM Card

If the preceding option did not work, try using a different SIM card. Turn your smartphone off, remove your SIM card, and insert a new SIM card into the tray. Check to see whether the problem notice shows when you turn on your iPhone. If not, the issue is most likely due to your SIM card. For a replacement card, contact your carrier.

Solution No.5: Carrier Settings Update

In many instances, updating the carrier settings resolves the problem. It’s a straightforward procedure:

  • Go to Settings
  • Tap on General
  • Tap on About

If a carrier settings update is available, you will be prompted to change them right away. Update by pressing the Update button.

What to do if your iPhone says Invalid SIM card or SIM card failure?

The no SIM card installed problem on your iPhone isn’t the only sim-related warning you’ll see. Invalid SIM cards and SIM card failures are also common. While the causes of all error messages are essentially the same, these two most often occur because the sim card has migrated or is damaged. An invalid sim card or sim card failure may appear if you recently removed the sim card from the phone while it was switched on. These messages were reported by several jailbroken iPhone users. If your smartphone has been jailbroken, the only method to solve the issue is to unjailbreak it.

Here are some ideas for how to repair an iPhone with an invalid sim card or a sim card failure:

  • Restart your iPhone
  • Turn off your phone and remove the SIM card. If the card is damaged, contact your carrier for a replacement. Clean the tray and the card. Put the card back into the tray, but make sure the SIM card is properly placed. Turn your phone back on.
  • Try another SIM card.
  • Update your iPhone to the latest version of iOS.
  • Restore your device to factory defaults using iTunes.

Every new version of iOS offers speed and security enhancements, as well as bug patches. It may, however, jolt your smartphone a little and create some problems, which typically go away after a few hours when your gadget settles down. If the iPhone has no sim installed, invalid card, or sim card failure errors persist even after a few hours after the update, try the following solutions:

  • Toggle Airplane mode
  • Restart your device
  • See if the carrier settings update is available
  • Reset network settings
  • Reinsert the SIM card
  • Restore your device to factory defaults using iTunes.

If nothing else works, contact your carrier or go to an Apple Store in your area.

After water damage, iPhones may have no SIM card inserted, an invalid SIM card, or a SIM card that has failed.

Water will harm your sim card if you do not do so. Even if you can switch your iPhone back on and it works, one of the error messages may appear. While you may attempt the options we’ve provided, you’ll most likely need to contact your carrier for a new sim card.

On iPhone 4, iPhone 4s, iPhone 5, iPhone 5s, iPhone 5c, iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7, and iPhone 7 Plus, these issues/solutions have been discovered and are effective.
