Phone numbers

Note that only SMS text messages (Green) use your carrier's SMS service and therefore those phone numbers show up on your billing statement. iMessages (Blue) or WhatsApp or Facebook Messenger etc, use WiFi or Cellular Data and work through the Internet and therefore the phone numbers are not registered separately.
