We have a sign up form with
* A country selector
* A phone number input field
We now have at least two options
Option 1
When the user chooses their language, automatically show the country code in
front of the phone number field.
In that way users don't have to worry if they should put in their country
code or not when entering their phone number.
Option 2
Do nothing. However, the system accepts 00(country code), +(country code)
and no country code at all.
In that way users can enter their phone number as they like.
