Yes. Postpaid plans bill you once a month, but you pay after the service period ends. Your bill covers the month you just used and can include the plan price, device installment payments, add-ons, overage charges, taxes, and fees. That is why postpaid bills can change from month to month. See our breakdown of the average phone bill in the US for typical totals. Prepaid plans are also monthly, but you pay up front, so you know the price before the month begins. Our prepaid vs. postpaid comparison covers the tradeoffs.
