Does any sim card activate Iphone 4?

I just got my Iphone 4 and I live in Algeria, I have a sim card called "Mobilis" and I'm gonna cut it to make it nano or something, and I don't know if it will work or not, My question is: Do all sim cards activate Iphone 4? Cause I'm stuck in the activation screen

You need to plug it into a computer to activate it. If your iphone is not tied to a specific wireless provider (unlocked), then you can use whatever carrier you choose, as long as they use a comparable GSM.
