This article will help you understand the possible causes and solutions for the problem that iPhone shows no SIM Card is installed. It also highlights the points to be kept in mind if you experience such a problem of iPhone not reading SIM Card in the future.
Let's find out the ways to deal with the problem.
1. Turn on Airplane Mode and Turn It off
This is an easy and simple remedy. Visit Control Center and tap on Airplane icon. After about ten to fifteen seconds turn the mode off and see if the SIM Card is getting detected.
2. Clean the SIM Card Slot
The SIM Card tray slot must be kept clean and dust free at all times. The dust that gets accumulated in the slot prevents the sensors from detecting the SIM.
Ensure this by first ejecting the SIM tray and then cleaning the slot with an unused soft bristle toothbrush or with a paper clip. Now re-seat the SIM in the tray and place them back in the slot carefully to avoid your Sim card stuck on iPhone.
3. Check the SIM Tray
iPhone SIM Card tray can be ejected from the slot by using a simple paper clip. Insert the clip in the small hole on the tray and press lightly. The tray automatically pops-out. Now pull the tray out of the slot. Carefully examine that the tray is not disfigured or damaged. It must hold the SIM Card firmly. If the tray seems to be lost, i.e., it does not hold the SIM properly or does not fit in the slot exactly, contact your nearest Apple Store to fix it.
Please DO NOT use another device’s tray in your iPhone. It could damage your SIM and iPhone permanently.
