Most Samsung phones contain very similar menu settings and every phone model includes a "Vibrate" mode. You can set your phone to vibrate by opening the "Phone Settings" menu on your mobile device. In this mode your phone will vibrate whenever it receives an incoming call, text or voicemail.
Turn on your Samsung cellphone. Wait for the device to start up.
Press the "Menu" button on the phone. Select the "Phone Settings" option.
Select the "Sound Profiles" option. Scroll down the list and select the "Vibration."
