I have checked as you advised but all I could see is ....Cellular data on/off,...Data roaming on/off...Apn settings....Sim pin....Sim application. That's all. Does this mean that my ipad wi-fi + 4G is defective and not really 4G? The pack/case of my iPad reads MD368B/A iPad wi-fi + 4G 64GB Black. Bought online from apple store uk. and delivered on the 16th of march 2012. Please let me know how to activate the 4G.
