Q: iPhone 4 runs without a SIM after iOS 7/7.1.1 update?!
After installing iOS 7 and all the latest update by using iTunes on my iPhone 4 I now have the problem that when starting the phone without a phone card I get the information that the SIM card is blocked and that you have to slide to unlock, the same information you usually receive when such a card is inside. Once unlocked the code screen appears asking for the PIN. The iPhone runs after having entered the PIN and you can open and work with all the apps which don't need an access to the internet like Calendar, Notes, Settings etc.. What has gone wrong? Can anybody help me please. Remain: There is no SIM inside the iPhone 4 when putting it on.
iPhone 4, iOS 7.1.1, 32 GB

Hey there kirsch,
It sounds like your phone is acting as though you have a SIM card in it when you dont. I would use the following troubleshooting to help troubleshoot that named:
iPhone: Troubleshooting a cellular data connection

- Toggle airplane mode: Tap Settings, turn airplane mode on, wait three seconds, and then turn off again.
- Restart your iPhone.
- Make sure that your software is up to date:
- Check for a Carrier Settings Update: Tap Settings > General > About.
- Check for an iOS Software Update: Tap Settings > General > Software Update.
Note: Some updates may require a Wi-Fi connection.- If your SIM card has SIM PIN enabled, try turning it off: Tap Settings > Phone > SIM PIN.
- Reset network settings: Tap Settings > General > Reset > Reset Network Settings.
- Restore the iPhone as new.
- If none of the above steps resolves the issue, contact your carrier, make an appointment at an Apple Retail Store, or contact AppleCare to troubleshoot further.
Thank you for using Apple Support Communities.
Cheers,
