I recently noticed that I am getting charged data even though I am connected to my Wifi at home, my tablet has NEVER left my house, has ALWAYS been hooked to my wifi, I had asked a representative about it, he said make sure you just turn of the mobile data on the device, so, I did that, on my phone when I was home, because I am hooked to the wifi and the droid tablet, I turned the mobile data off on that AND turned the tablet OFF for a whole week, and they are STILL CHARGING ME ON MY DATA PLAN!!! This is not right! Bet a lot people never notice this and this is how they are making money off of us, by adding data usage on there that really isn't being used!! I'm sure I am not the only one this is happening too???!!
