Mobile phone number

Problem

There are several bugs related to the mobile phone number (and it works with a hidden scenario). Here are what actually happen:

- In Socolissimo step, if the shipping address is not fill with valid mobile number in the phone number section (phone_number), it will ask for the mobile phone number.
- When it gets the mobile number, it tries to fill it in the phone number of shipping address if this field is not empty.
- Later, the phone number field is used in the Expeditor Inet export.

Thus, I enter a 01 number (fixed number in France), I'll be asked for a 06 or 07 number (mobile number in France) in the next step, but this number is not used and by 01 one is used instead.

Solution

1/ A temporary solution is to hide mobile and fax number, and use the phone number field as if it were a mobile number field.

2/ A permanent solution is to use the mobile number field. However data could be lost with all past orders (they can have 06 number in "phone number", and "mobile number" empty). We can add a fallback: if mobile number is empty, use the phone number as if it were a mobile number.
