Part 1: How to fix the 'No SIM Card Install' problem on iOS devices?

Remember: The following steps may result in loss of important data and that is why we strongly recommend you carry out a data backup for your iOS device before carrying out the following steps. The possible solutions and steps to follow them are mentioned below.

Step 2. There is a pin hole on the SIM Tray of the iPhone. Insert a paperclip into it or a tiny clip that comes in the box when you purchase an iPhone. Press the clip firmly into the hole and the SIM Tray shall be ejected.

Step 3. Now examine the SIM card and the SIM tray. There might be some dust, debris or even gunk on it. Using a soft, damp cloth, wipe the card and the tray clean and wait until it is completely dry before you place the card back onto the tray and push it back inside.

Solution 3: Wireless Carrier Settings with iTunes have to be updated
