How to remove the area code in the Phone number field?

1 - ok now what about the phone number section, how do i remove the area
code as an option? Its not helping, its getting in the way

Is this the form that you are referring 91697240543158? 

Unfortunately, it is not possible to remove the Area Code portion for the phone number field.  The solution would be using a Short Text Entry field instead of Phone. And you can set the Validation to Numeric, you can also use Input Mask if you wish.
