Hello, I used to live in US and moved to France; I received from AT&T instruction to unlock my Iphone, but I lost the SIM card, and for the process the original SIM card is requested, if someone can help me on this matter - Thank you

You cannot complete the unlock without a SIM card from the original carrier. It would not need to be an active SIM, but a SIM does need to be present.
There is no way around this, unfortunately.

You don't really need AT&T SIM card for the unlock. Just pop in any SIM that you have and then try getting it unlocked.
