Do I need to reactivate my iphone when I restore it? - 1

I want to restore my iphone 4 ios 6.0.1 so I was wondering if I would have to reactivate the iPhone with the SIM card.

I think yes you can reactivate your iphone.

No restore deletes things that are nit needed

You will not have to change the sim card
it will still work after you restore the iphone
Have a good day
