A:Answer Razer Kishi Controller doesn't have Bluetooth or another technology that allow it to be pair with, it just can be plug into a smartphone via USB Type-C or Lightning depending wich model you bought (Android or iPhone) and the extra connector that it have is use explicitly to charge the phone. Now, if what you want is to use two controllers at the same time to play with a friend, it could be possible, but not sure if there are smartphone games with coop options like Nintendo Switch does.
