Unlike a majority of cell phones, the iPhone's silent feature is situated around the phone's border, not as option within the phone. Knowing how to find the silent mode on your iPhone will allow for calls and texts to be received via vibrations, a quiet approach to notifications.
Locate the silent mode switch on your iPhone. The switch is on the top left-hand side of the phone, above the volume control and below the corner of the phone.
