WHY ARE THERE TWO CHARGES ON MY BILL?

As a Postpaid customer, you receive a monthly invoice where you're charged for any activity that has occurred during your monthly bill period (30/31 days).

UNLIMITED and data-only plans operate on 28 day cycles, which means there can be instances where two plan renewals may fall within the same monthly bill period - this can happen if your plan renews immediately after your bill period has begun.
