When you open the phone/dialer app you should see something like this

or one of the screens I could swipe across to but can't for obvious reasons..
See that circle with the 10 dots in it?if you press that it will being up the dial pad
(this is my phone and all phones are different so I'm sorry if this looks nothing like yours).
What phone are you on?
