NO SIM problem can happen to iPhone and iPad. It happen because the sim card is not connected to it place. This method is worked for me. And i Hope it work for All of you too. Here's the method: 1. Remove the sim card 2.Remove the Touchscreen, LCD and LCD Shield Plate. 3. Push down firmly at sim card slot. (Like pushing a button) 4. Insert the sim card, and see.
