If you're using a cell phone ( i dont know if the service matters, but mine is sprint) and you have free minutes after a certain time, does your bill at the end of the month still show the record of who you spoke to after that time? And if it's free minutes after like 9pm, it's usually till sometime early morning, right? not till midnight or anything? Is there any way to make the records not show the calls made during the free minutes? Thanks.
