The iPhone can vibrate when you receive a phone call, text message, or notification even if the iPhone is in silent mode (when the ringer switch is set to mute). Turning on vibrate is simple and is done in the iPhone’s Settings. Below are step-by-step instructions for how to turn on vibrate in silent mode in both video and text format:

1. Tap the Settings icon:
2. Tap Sounds:
3. Under Silent, swipe Vibrate tab to On:
And that’s it. The iPhone should now vibrate to let you know there is a call, text message, and notification when the ringer switch is set to off.
Note there is a second Vibrate option further down in the Sound settings. Turning on this option will make the iPhone vibrate alongside playing the ringtone (in other words, when the iPhone’s ringer switch is set to on and a ringtone plays when you receive a call or text message). It will cause quite a racket, but it is also more likely to get your attention when a call comes in.
