Could I use the same sim card for my iphone 5?

Okay, so i already have the iPhone 4s, but recently got the iphone 5 off kijiji, but i was wondering if i could just put my same sim card that i have in my 4s in the 5? Can someone help me, thanks!

You would have to cut it into nano size cause iphone 4s uses micro size

Yes, of course. But you've to be sure the iPhone 5 is unlocked or locked to the same carrier your iPhone 4S is locked now. You can mail this person (arghyle@rocketmail.com) who can help you factory unlock your iPhone 5 if it's locked to a different carrier.

No. You will need to get a nano sim card. A normal sim card can be cut down in size to a micro sim card. But you can't cut a micro sim card into a nano sim card.
