Hello, I already had the same keyboard on another site As I am satisfied 99% of its use, I wanted mm in the countryside I thought that the receptor on the cell would work with one or the other, it does not work the frequency is not the same This little keyboard is very nice, it has large keys and a numeric keypad The only complaint is the lack of a small LED that it is turned on and eventually the battery charge status For the price, I recommend When deadlines and delivery is Amazon !! so perfect
