Your Lumia phone will automatically upload the phone contacts to your Microsoft Account (formerly Windows Live ID) you created at initial set up (It is a requirement to have a Microsoft Account username as this is your ID). Whenever in the future you add, remove or amend a contact on your phone, your account will be updated (synchronised) in the background (over the air / wirelessly).
