it doesn't need one to operate. The SIM card is only needed for activation on a "phone plan." It allows you to use 3G but other than that this is just as good, if not better than any other tablet.
It does have 16 gb of internal storage(also a spot for an SD card) but Android 3.2 is just an update. As I've done a factory reset, updates would have to be re-downloaded.
syou can do everything with it as any oter tablet? ive never bid on one that could use a 3g connection (to my knolage anyways :) it works fine with just wifi,and it has the google play store preinstalled ?
Yep everything works great. Like I stated in an earlier comment, it doesn't have a SIM card/isn't activated. So, at this point it just uses wifi until the winner activates it.
