Hello. Welcome to Android Central.
You don't need a sim. You can attach it to a pc via usb, turned on and with any secure pin/pw Lock Screen removed, just swipe or no lock - if the computer recognises the device as a new drive, open to find the DCIM folder for photos and videos. If it's not recognised in My Computer / Windows Explorer or mac, download Samsung Kies to the pc if you don't have it, and it will install the correct drivers when connected.
