How to restore when the sim card I put in my iphone says INVALID SIM?

So I had done a factory unlock and the next thing I needed to do was restore on itunes with the sim card I want to use. But when I put the sim card in it says INVALID SIM. So how am I suppose to restore if itunes won't let me restore cuz my phone says that? How do I get rid of the invalid sim before restoring?

Check the Sim card for any smears or scratches that may be present on the card. This could possibly cause it to say invalid. If not that, Youtube might be your best answer!

It's Your Phone I-phone? If It says Invalid Sim it's locked to network, you need to unlock it… You can get Remote Unlock service at http://www.mobileunlocksolutions.com/ and Unlock it easily. Find the network, country it locked now and specify it. Then get remote unlock service and unlock it. Then you can restore your phone by visiting nearest Apple Store.
