I just got my phone Dec 3 and it says the bill date is/cycle ends on the 9th. I have a $30plan but my first bill says I owe 42$ ...30+txes and a 7partial fee.... Why am I being charged a full montj? Shouldn't I just be charged for the partial use dec3-9?
That's the way all carriers work. Every month you pay for your plan for the month you are going into, plus any usage or overage for the month you have just finished. Your first bill will also include charges for the partial month to get the ball rolling.
