I understand that you would like to connect your Logitech Wireless Wave Combo MK550 to the Galaxy S III cell phone. This combo was design to work with computers (desktop, laptop), so that's why it won't connect to your cell phone, please check out the following link:
Under Specifications, you'll find the System Requirements to connect this combo to a device.
Please let me know if this information helps.
