How to unlock and activate my iPhone 4S OS 6.1.2?

I do not have my original sim card, only the one I want to unlock it for. I also need to activate it, as I can't bypass the "Slide to set up" section.

I have recently updated it and restored it.

If you want a cheap and permanent iPhone unlock, then use the site that I used. They quickly unlocked my phone in under a day. And the price is fair too!
