No SIM card notifications, with a SIM card in the tray?

[Kyle_Wallpaper]

So one day I decided to check and see what my SIM card looked like and opened up the SIM card tray. The SIM card popped out of the tray thing because of a long history of difficult to remove SIM cards, I hadn't expected it to not be secured in the tray. So I picked up the SIM card, and I happen to know nothing happened to it when it fell onto the carpet, and put it back into the tray and closed it.
However it still says no sim in the corner and will not let me access the cellular data. I turned it off and back on, but still it says there is no SIM card even though there is in fact a SIM card In it. I took out the tray again, turned it off, put the tray in, and then turned it back on, and still the same.
Will I have to take it in somewhere or something, or will I be able to fix this myself? Help, please.

I suggest you take the phone to your carrier and see if they can offer some assistance.

Why don't you rub the sim card on your pants or a clean cloth to clean it. Put it back in the tray afterwards and it will work again

That seems to have don't the trick, thank you.
