Does My MetroPCS SCH-R570 Messager III Phone Have A Speakerphone?
Yes, the Speakerphone button, located above the green SEND key, functions as the Speakerphone button. Press it to enable the phone’s Speakerphone. The speakerphone icon will appear in the top left corner of the display. Press it again to disable the Speakerphone for privacy.
Due to higher volume levels, do not place the phone near your ear when using the Speakerphone feature
