Say your minutes started over on Jan. 10th.
You got billed on Dec. 29th and again on Jan. 9th. (Family Plan)
Your next billing will occur on Jan. 29th....and again on Feb. 9th for the billing cycle.
Is this billing for the month before (december) or for Jan.???
HEELLLP....

I know when you very first get your bill then say you activate today the 23rd and your bill cycle is the 17th. Then your first months bill will be from the jan 23rd to feb 17th plus feb 18th-march 18th. The bill would spit out on feb 17th and would be due 21 days after the cycle. You always pay a month in advance on your first months bill. I hope that helps you out.
