How to fix an Invalid SIM or No SIM Card installed on iPhone 15 Pro
Check with your phone carrier to make sure your account is valid
Your phone carrier may not have activated the SIM card yet, or your account may have been deactivated due to a specific issue that needs to be addressed.
The first thing you should do is to check with your wireless network operator. They may help you. They may have to replace your SIM. Make sure that your account is in good standing e.g., you do not have any unpaid bills.
Toggle Airplane mode
Try toggling Airplane Mode on and off to re-establish the phone’s network connections. Bring up the control center by swiping down from top right part of your iPhone’s screen. Now tap Airplane mode. You can also go to Settings and toggle Airplane mode on and off.
Check the SIM card
The next step to fix the Invalid SIM or No SIM Card installed error on iPhone 15 Pro is to check the SIM card. Remove your iPhone SIM card from the SIM card tray and then put the SIM card back. Make sure that the SIM tray closes completely and isn’t loose. Now check if the error has gone away.
A dirty or damaged SIM card might also cause this issue. Clean the SIM card before you insert it into the phone again.
If you still see an alert about your SIM card, try using another SIM card. If you don’t have one, go to your carrier’s retail store and ask them to test with another SIM card. If the other SIM card works,get a new SIM from your network carrier.
Check the phone hardware problems
Ensure that the phone’s SIM tray isn’t bent or damaged. If the tray doesn’t release easily or you need to force it back into the phone, you might have to replace it. You can confirm whether it’s a hardware issue by checking the SIM card on another phone. If it works on other devices, you likely have a hardware problem on your iPhone. Contact Apple support or a licensed repair outlet for further help.
Restart your iPhone
If you’re getting the ‘invalid SIM’ or ‘no SIM’ error on your iPhone 15 Pro because of a temporary software glitch, a simple reboot might fix the problem. Press and hold the Side button and either of the volume buttons to bringup the power off menu. Drag the power off slider from left to right to turn off your iPhone. Now check if your iPhone 15 Pro can read the SIM card.
Check for updates
If you are still getting an error, it’s time to check that all the updates are applied.
First, navigate to Settings > General > Software Update, and check to see if there is any pending update.
Next, check for an iPhone Carrier Settingsupdate. As the name implies, these are settings from your phone carrier that enables you to use their service efficiently. In various parts of the world, including Europe, it will be called Networkinstead.
You will usually be notified if there is a carrier settings update, but you can manually check by going to Go to Settings > General > About. If an update is available, you’ll see a prompt to select OK or Update.
Reset network settings
You might have to reset your iPhone’s network settings if nothing else works. Go to Settings > General > Transfer or Reset iPhone > Reset and tap Reset Network settings. Keep in mind that this will also reset your Wi-Fi and Bluetooth settings. But if your iPhone 15 Pro SIM card is still not working, it might be worth the inconvenience.
Contact Apple Tech Support
If you are still getting the Invalid SIM or No SIM Card installed error, then it’s almost certain your iPhone 15 Pro has a hardware problem. The best thing to do is to contact Apple Support and arrange for the phone to be sent back for repair or replacement.
