Some users have experienced a sim card not detected after ios 16 update issue. If you're also a victim of this issue and your sim card is not working after the iOS 16 update, don't worry. Here are 5 ways you can solve this issue.

Way 1: Turn Airplane Mode off and on

iPhone users who are experiencing sim card not detected problems after the latest iOS update may be able to fix it by turning Airplane Mode on and off. To do this, follow these steps.

  • Open Settings 
  • Tap Airplane Mode
  • Turn Airplane Mode on 
  • Turn Airplane Mode off 
  • Attempt to connect again.  

If that doesn't work, turn airplane mode back on and connect to cellular data instead of Wi-Fi. Other possible fixes include resetting the network settings or reinstalling your sim card.

Way 2: Restart iPhone

The best way to fix the sim card not detected after the iOS 16 update issue is to restart your iPhone. To do this, press as well hold the Sleep/Wake button until you see a slide to power off on your screen. Press and hold that button until your iPhone turns off, then turn it back on again. I should help get things going again without any other troubleshooting needed. If, for some reason, it doesn't, continue onto Way 3.

Way 3: Insert SIM Card Again

If you have tried all of the other methods and your SIM card is still not detected, try inserting the SIM card again. Make sure to install the SIM card in the right way and that it's inserted deep enough into the slot.

If you're having trouble inserting your SIM card, ensure your fingers are free from oils or dirt by washing them with soap and water before trying again. Be patient while waiting for your device to detect your SIM card. It might take some time, so don't worry if it doesn't happen immediately. It might be helpful to remove your SIM card and reinsert it if the issue persists.

Way 4: Reset All Settings

If the sim card is not detected due to the iOS update, resetting all settings might help. One can do this by going into iPhone Settings > General > Reset All Settings and tapping Erase All Content and Settings. It will wipe out anything that might have caused the problem, but it will also remove any information stored on your phone.

It's also possible that you won't see this setting unless you're using an older device. On newer devices, tap General at the bottom of the list in Settings and then tap Storage & iCloud Usage under Device. There you'll find a button for Reset Storage which does pretty much what it sounds like.

Way 5: Check for a Carrier Settings Update

If you have been experiencing problems with your cellular connection after updating to the newest version of iOS, you can try one more thing. Check if your carrier has an update that could fix any issues. Start by opening Settings and scrolling down until you see the Cellular option. 

Tap on it and check for updates from your carrier. If there are any, download them and restart your phone before trying again. Otherwise, contact your carrier or Apple Support. Furthermore, you might want to check with your mobile service provider, as they might be able to issue you a new SIM card. 

Part 5: Is It Possible to Use My iPhone without a SIM Card?

Using your iPhone without a SIM card may be possible, but there are limitations. It will be impossible for you to make calls  or send texts, and you'll have to rely on Wi-Fi for data. In the same way, an iPod touch can be used without a SIM card; the iPhone can also be used without one.

You can use the iPhone without a SIM card as a Wi-Fi-only device to send iMessages, listen to Apple Music, FaceTime, watch podcasts, and play iOS games you've downloaded. To conclude, there are no limitations to the iPhone with no SIM card other than being unable to make calls and send texts.
