Hi folks. I have an AT&T Galaxy Tab 8.9, unlocked by them. Ive been told that it does have the ability to make phone call (Of your sim which is inserted on the top right edge) form it, BUT, this part of the system is hidden / disabled. Can any oen advise how to activate/ open this so I can use my tab to receive and make calls? Seems really stupid that this is the only tab that can not be used for call. Whats the point?!!! I am in Africa so can not go back to AT&T to sort it out and their service off-shore is quite useless and costs a fortune in phone calls. Please email me direct as this is urgent firstname.lastname@example.org God bless Matt PS, WARNING; IF YOU USE AT&T MOBILES OR TAB IN A COUNTRY WITHOUT CONTRACT TO AT&T THEY WILL CHARGE YOU $19.80 per MEG!!! 1ST PRIZE TO AT&T FOR THE most EXPENSIVE DATA IN THE WORLD!!
