Many Apple users are experience problems with their iPhones not detecting SIM cards. When an iPhone fails to recognize the SIM card , it is unable to connect to a mobile network, make or receive phone calls, or send text messages. But, if you see the message “SIM Card not detected” on your iPhone’s home screen, it’s not a great concern; it’s something you can generally fix at home. Here, I’ll explain the various causes and solutions if your iPhone fails to identify a SIM card.
Smartphones as well as push-button phones, even brand new devices, can stop seeing a SIM card. No need to rush for a repair. Instead, you should first investigate the source of the problem.
Airplane Mode, first, should be turned on and off. This is a straight-forward potential solution. Tap on the Airplane symbol in the Control Center. Turn off Airplane mode after ten to fifteen seconds and check to see if the SIM Card is identified.
It is also possible to test if your original SIM is compromised by using a SIM card that isn’t yours. If your iPhone fails to read your SIM card, just call your carrier’s retail outlet and request a new SIM card, or simply replace the old one if another SIM card can be recognized.
Another possible reason the SIM card isn’t being identified is because your celluar phone carrier may have changed the settings for how the iPhone connects to its network, something you’ll need to update. See if an update to the iPhone’s operating system is available. Make sure you’re connected to the Internet or have a computer with sufficient battery power before proceeding. Check for any available updates, download and install them, and then check to see whether the problem has been fixed.
If your iPhone still doesn’t detect your SIM card, having tried everything else, here’s what you might do next. First, using iCloud or iTunes, make a backup of all your information and data on your iPhone. Then, remove all data and settings from your smartphone. Go to Settings. Then, General, Reset, and finallyErase All Content and Settings. This completely erases all data and settings from your iPhone, making it as good as new.
