How to unlock iPhone 5c-should I restore it or just simply insert a sim?

I just used ebay to unlock my 5c on ios 7.0.6. They said my phone is unlocked and I can go ahead and activate it. The phone was originally vodafone Ireland and on their website the say I must insert a vodafone sim and restore the phone to unlock it. I know on the iPhone 4 you just plug it into iTunes and its done but what's the easiest way for my 5c?

It is the same as with iPhone 4. No difference. Just plug it into iTunes. Check more in the link below.
