How to read a business wireless bill
A business wireless bill has three kinds of charges, and on a large account each one repeats for every line.
A drawn outline, not a copy of any bill. Carriers lay out their bills differently.
Plan charges
Most of a wireless bill is plan charges: one monthly rate per line, plus add-ons. Check each rate against your contract, and each plan against what the line uses over several months. A line that shows no usage at all is worth a closer look before anyone cancels it.
Equipment and one-time charges
Device payments run for a fixed number of months, and promotional credits are meant to offset them. Check that each credit shows up for as long as it was promised, and that one-time charges such as activation and late fees were agreed.
Surcharges, taxes and fees
Carrier surcharges, such as administrative and regulatory charges, are set by the carrier, while taxes and government fees are passed through as billed, so it's worth reading the two separately.
Telecom bill glossary
What makes up one line's monthly charge
The sizes are an illustration, not taken from any bill.
- Zero-usage line
- A line that bills every month and shows no calls, texts or data. Often a spare, or the line of someone who has left.
- Usage report
- The carrier's export of each line's calls, texts and data for a billing cycle. On a large wireless account, it's one of the documents we ask for at the start of a review.
- Device payment
- A monthly installment on a phone or tablet, billed for a fixed number of months alongside the line.
- Promotional credit
- A monthly credit that offsets a device payment or a plan charge for a set period, if the line stays active and eligible.
- Early termination fee
- What a carrier charges to end a contract or a device agreement before its term is up.
- Carrier surcharge
- A charge the carrier sets and lists near the taxes, such as an administrative or regulatory charge. It isn't a government tax.
- Letter of authorization
- A signed letter that lets a carrier discuss your account with a named third party and act on the changes you've approved.
