Invalid sim on my phone
좋은 질문 입니까?
In my experience this is most often an issue with the SIM card. Or the SIM just needs to be reseated.
But the iPhone Invalid or No SIM might get you some additional fixes you haven't tried.

it's probably an issue with your sim card reader or your sim card itself contact your sim card company for a new one and try that. if that does not work you will need to replace the sim card reader in the phone.
I hope this helps,

Dirt or corrosion may have built up on one of the contact pads, try compressed air to see if that works before opening up the phone.
