Just updated to iOS 9.3.1 but getting the iTunes error “There is no SIM card installed in the iPhone you are attempting to activate”? Try these possible fixes.
Updating your iOS can be a tricky situation because you might get unexpected error such as this one. This is a rather weird issue because you already have your SIM card inserted but iTunes is saying otherwise.
There may be some versions of SIM cards which are not tested with the latest iOS version. This is usually the root cause of the problem.
Some older SIM cards from 2-3 years back have compatibility issues with the latest iOS. Although this is not mentioned in Apple’s release notes, this issue had happened during the release of iOS 6 a few years ago.
Back to the issue at hand, try the following fixes:
1. Take out the SIM card and insert it again (you may have to do this multiple times).
2. If that doesn’t work, try using a newer SIM card (friend’s, wife’s, colleague’s etc). Some old SIM cards are not able to activate iPhones running on iOS 9 and above.
3. If that still doesn’t work, visit your nearest network provider and get a replacement SIM card. Be sure to try your iPhone there and then.
Alternatively, if there’s an Apple Store near you, the Genius Bar may be able to assist with this issue as well.
If all fails, there’s a chance that of hardware failure with your iPhone. As strange as it may seem, updating the iOS can be an unpredictable adventure itself. If you’ve experienced other iOS related issues before, doing a full restore iTunes may help in some ways.
