Some users<\/a> have been seeing one of various SIM card related error messages, such as SIM Failure, Invalid SIM, No SIM, No SIM Installed, etc., popping up on their iPhones. You may also have seen a notification like Searching<\/a>, No Signal, or SOS<\/a> on the iPhone’s screen. <\/p>\n\n\n

Are you encountering SIM card related errors on your iPhone after an upgrade, causing the absence of cellular signal bars? If your SIM card does not work due to these errors, making calls, using mobile\/cellular data, and sending or receiving SMS texts will not be possible. As a side note, you may still be able to send iMessages and make regular Wi-Fi calls<\/a>. The good news is that you may be able to troubleshoot and resolve the issue quickly. <\/p>\n\n\n\n

Please try following the steps below, in this order, until your issue has gone.<\/p>\n\n\n\n

1. Turn Airplane mode on and off<\/h2>\n\n\n\n

Begin by navigating to iPhone Settings <\/strong>or the Control Center <\/strong>and enabling Airplane<\/strong> mode. After a 15-second wait, disable Airplane<\/strong> mode. If your carrier name appears in the status bar or Control Center, it indicates that the SIM card is functioning properly. <\/p>\n\n\n\n

2. Restart your iPhone<\/h2>\n\n\n\n

Restarting is always a good idea. Restart your device to see if you can fix this issue. If you are just starting to use a new SIM card, always restart first. <\/p>\n\n\n\n

3. Update your iPhone<\/h2>\n\n\n\n

Apple may have released a new iOS 17 version to address this problem. Go to Settings<\/strong> > General <\/strong>> Software Update<\/strong> to check for updates. If there is an update, follow the instructions on the screen. <\/p>\n\n\n\n

4. Check for a carrier settings update<\/h2>\n\n\n\n

Especially after major iOS releases, carriers may release updates to ensure that their service is working perfectly with iOS. These types of updates do not occur often. To check this, go to Settings<\/strong> > General<\/strong> > About<\/strong>. If there is an update, a popup will appear. Please ensure that your iPhone is connected to Wi-Fi, as this requires an active internet connection. If you do not have Wi-Fi, find a Wi-Fi and try this step again. <\/p>\n\n\n\n

5. Check to see if your SIM card is damaged<\/h2>\n\n\n\n

Remove the SIM card from your iPhone, wipe it gently with a soft, dry cloth and place it back in. Please note that this step is applicable for iPhones with a physical SIM card. Not all iPhone models have SIM cards, as some iPhone 14 and 15 models only have eSIMs. <\/p>\n\n\n\n
