How to fix iPhone No SIM card installed issue for real?
For iPhone users, the specific iPhone No SIM error means that the device is unable to communicate with the SIM card and the continuity between the voltage terminals on the SIM is somehow getting disconnected. There are several valid and working reasons behind the error. If you are getting an error or the cellular bars are missing then the following workarounds can be given a try
Check if SIM is valid and working
First and foremost, check if your SIM is active with a telecom provider and iPhone is unlocked. Go to Settings>>Mobile Network>>SIM Card Information.

You may need telecom operator assistance if you discover 4 question marks against the signal strength indicator in Settings.
These instructions should be followed if you receive a message that states “Invalid SIM” or “No SIM Card Installed.”
1. Verify that you are enrolled in a plan using your wireless provider.
2. Restart your iPad or iPhone.
3. Look for a carrier options update. Go to Settings > Privacy > About. You’ll be given the option to choose OK or Update if an upgrade is available.
4. Take your SIM card from your iPhone or iPad and replace it in the SIM card tray. Verify that its SIM tray snaps shut securely and isn’t loose. It could not fit properly when you’re using a SIM tray from an iPad, iPhone, or another phone manufacturer that isn’t the same model.
5. Attempt a different SIM card. If you do not have one, visit the retail location of your carrier and request them to conduct a test using a different SIM card. Your SIM card might need to be changed.
6. Contact Apple support or visit the nearest Apple center if you continue to notice an alert iPhone No SIM.

If it doesn’t, take the SIM out and inspect the card and slot for dirt. Clean them if they are. Blowing into the slot is likely acceptable, but pressurized air is always preferable.
Close SIM Tray Completely
Ensure that the SIM card tray on the side of iphone is completely sealed else the card may not get entirely slotted in causing the No SIM error.
