what are some video chat apps for android AND old iphone?

you cant video chat without a front facing camera and the old iphones dont have them and phoenix aint a very good phone so it deff dont have a front facing camera (if im wrong im sorry just what i read said it didnt) so you really cant video chat i no thats not a good answer your looking for its just how the programs are set up. and as for skype as far as i no skype dont allow "video" on android at all just talking. so to sum it up you cant video chat with those 2 platforms sorry again i no its not the answer you want
