Many owners of the 4S are experiencing problems with SIM card messages; the new iPhone has had a handful of issues since release, such as battery life being poor etc.
The poor battery life is associated with iOS 5, some have experienced problems with phone calls, and even Wi-Fi and network issues, and now a few customers are reporting “iPhone 4S No SIM Card Installed” problems.
We have had a few emails about this new problem, so we decided to look into this a little more and visited the Apple’s discussion forum. In some of the emails, iPhone customers said that they were having SIM card issues and by turning off the smartphone and then booting back up normally fixes the problem, but this should not be the case when you spend so much money on a new phone, it should work properly from get go.
The battery life problem is wide spread, this is not the case for the iPhone 4S No SIM card installed, it seems to only be a certain few complaining. So we want to dig even deeper and ask our readers if you are having these problems.
Are you having SIM card issues on your iPhone 4S?
