Ipad and sim cards?
I just received a notice on my iPad (3) that it doesn't have a sim card....I didn't know it needed one? When I try to go to the cellular data features, they are all greyed out so I can't access them. I'm running on wifi right now....but when I go off, no celluar data, hence no internet, etc.
Any suggestions?
iMac, Mac OS X (10.7.2)
