iPhone not recognizing SIM card due to hardware problem. If your iPhone can’t find the SIM card because of a physical problem, you can also try the following tips.

Clean the SIM card slot

Always keep the SIM card slot clean and free of dust. Because of the dust that builds up in the tray, the sensors can’t find the SIM card.

Make sure of this by first taking out the SIM tray and then cleaning the slot with a paperclip or an old soft-bristled toothbrush. Now put the SIM card back in the tray and carefully slide it into the slot.

Check the SIM tray

A paper clip can be used to pull the iPhone SIM card tray out of the slot. Place the paper clip in the small hole in the compartment and lightly push down. The tray comes out on its own. Now pull the tray out of the hole.

Make sure the tray is not damaged or written on. The SIM card must be in his hand. If the tray seems to be missing, meaning it doesn’t hold the SIM card properly or doesn’t fit snugly in the slot, you can get it fixed at your local Apple Store.

Please DON’T put anything else in your iPhone’s slot. This could make your SIM card and iPhone broken for good.
