Ok so I want to buy my son an iPhone 5s on Saturday December 6 2014. But my phone bill is the next DAY December 7 2014 Sunday. I don't want to add on the line and get charged for it the next day on my bill. So I wanted to know if I can go to the store on the 6th and pay my phone bill early and then add on the line. So that way the bill won't go up right then because I will have already payed the bill. So the bill will go up for the next time. Is this possible. Can I pay my bill before hand and then add on a line to my plan? BTW the phone is $0 down so I won't have to pay anything in the stores.
