Learn why your phone bill is more than expected

Explore the most common reasons your phone bill might be higher than you expected.

Examples of common charges

Partial-month charges

  • These occur if you add or remove services in the middle of a billing cycle.
  • Services billed in advance are charged for partial month when added or removed during a billing cycle prior to the bill date. The actual partial-month charge depends on the number of days the services were used in that billing cycle.

Billed in advance

Certain recurring charges are billed one month in advance. These include custom calling features, calling plans, local calling services, and emergency 911.

Billed in arrears

Charges for local usage, long distance, and pay per use are billed in arrears (after the fact).

Promotional credits

Your promo credits may have expired on your most recent bill.


It may take one to two billing periods for discounts to appear on your bill. Please pay the full amount on your bill, by the due date, to avoid future billing issues.

International calls

It might benefit you to have a plan for international calls (PDF, 237KB).

  • Collect calls may have been accepted that you weren’t aware of.
