Hi NickRas, Your billing cycle starts the day you activate your phone or seven days after the phone is delivered—whichever comes first. The billing cycle ends 30 days later, and your payment is charged 20 days after that. Here's an example of how it all works:
December 6: Delivery of your new phone is confirmed.
December 13 (7 days later): Your billing cycle begins.
January 13 (30 days later): Your billing cycle ends.
February 20 (20 days later): Your credit card on file is charged.
