Hi there and welcome
They do sorry, its the only way to accurate bill an portray this.
But have your friend and you install Skype on the phones. Then you can over Wifi or even 4G talk for free and it wont show up on the Bill.
You can also message each other via Skype and none of this will come up on the bill. It also saves you money
If you would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
