Not able to put the Nokia E5 phone in Vibration Mode

When you get to your phone's setting, select profiles. Amongst the list of profiles, determine which of them you want to use to activate your vibrate mode.
When you have done that, scroll to that profile, select 'options', then select 'personalise'.
In the personalise sub-menu, you are allowed to set the features of that mode to your desire.
In the ringing tone, select no tone, in the ringing volume, reduce the volume to zero. When you are asked if you want to set the ringing volume to the maximum, select yes/ok.
In the vibrate option, select yes/vibrate.
In the message tone, select no tone.
For other sounds and tones, select no tone.
When you are done, REMEMBER TO SAVE IT.
Then go back and activate that profile.
It is advisable that the profile you use for this though, is your 'silent' profile.

Hope that was helpful?
Have a wonderful day.
