I need remove my number from iMessage and Facetime
iPhone 5
iOS 8.1.3
I need to remove my phone number from iMessage and Facetime, what I mean is that when I restore my iPhone after entering my Apple ID leaves me can contact me via iMessage and Facetime with my phone number and my two email addresses, but just let me get my email address but my phone number is grayed out and will not let me remove it. In simpler words what I need is that the next time you restore my iPhone when you get there do not include my phone number.
Excuse my English but only speak Spanish and use a translator online
