Restore Your iPhone To Factory Settings
CAUTION: This may brick your iPhone!
When you restore an iPhone, it uses a SIM card to activate itself. If your iPhone cant do this, it becomes totally unusable! You should only restore your iPhone if you have a spare phone to use should it go wrong.
We suggest restoring your device using DFU mode, which is the deepest level of restore possible. You can find the instructions to enter DFU mode for every iPhone here.
Alternatively, go to Settings> General> Reset. Choose to Erase All Contents and Settings then enter your passcode and Apple ID details when prompted.

Turn Off/on Airplane Mode
Another thing to get rid of the iPhone is saying no SIM issue, turn on the Airplane Mode at once and then turn it off again. Your iPhone not supporting SIM cards is pretty common, and almost every iOS device user faces this.
Heres the brief guide to turning on the Airplane mode.
- Open Settings and navigate to the Airplane mode option.

- After waiting for a few moments, you need to turn the Airplane mode option again to make things normal for your iPhone.

Your iPhones SIM card stores the tiny bits of data that distinguish you from all the other iPhone users over the cellular network, and contains the authorization keys that allow your iPhone to access the voice, text, and data services that you pay for on your cell phone bill. The SIM card is the part of your iPhone that stores your phone number and allows you to access the cellular network.

Before the iPhone 5, carriers like Verizon and Sprint who use CDMA technology used the iPhone itself to link a persons phone number to the cellular data network, not a separate SIM card that would be placed inside.
