Method 2. Make Sure Your iPhone is Not Locked

Some carriers sell iPhones that are locked, which means that they can only be used on the purchased network. If you find your iPhone is locked, you can contact the carrier or third-party unlocking services to unlock your iPhone.

Method 3. Make Sure Your SIM Card is Active 

If your SIM card is deactivated by the carrier, you may encounter this issue. Check if all the services have been enabled from the carrier. 

Suppose that the SIM card is indeed active, just get it replaced from your carrier and then the new SIM card will work for you. However, if the SIM is inactive, you need to make an active plan with your carrier.

Method 4. Check for a Carrier Settings Update. 

To fix iPhone SIM card not supported, you need to ensure that you have updated your carrier settings into the latest version. Simply go to “Settings” > “General” > “About”. If an update is available, you will see a prompt and then select “OK” or “Update”.

Method 5. Remove the SIM Card and Reinstall It

Remove your SIM card from the SIM card tray and then reinstall it to your iPhone. Make sure that the SIM tray closes completely after putting the SIM card back. 

Method 6. Fix iPhone SIM not Supported by Updating to iOS 12

There might be a compatibility issue with your SIM card before updating your iPhone to the latest operating system. Now go to “Settings” > “General” > “Software Update”. If there is an available update on your iPhone, you will see a red option at the right of “Software Update”. Then click this icon and tap on “Download and Install” to update to iOS 12.
