A $2.99 "service fee" on one line of a small business phone bill is easy to miss, and that is the point. The FCC says it receives tens of thousands of billing complaints each year and has estimated that cramming has harmed tens of millions of American households. Here is what to look for and what to do.
What cramming is
The FCC defines cramming as the illegal act of placing unauthorized charges on your wireline, wireless or bundled phone bill. It usually happens when phone companies let other providers bill for goods or services on their customers' phone bills, so a phone number works like a credit card number. According to the FCC, crammers may try to place a charge with nothing more than an active phone number.
Wireless lines need extra attention. The FCC notes that the more a mobile bill looks like a credit card bill (app purchases, other charges billed to your phone), the harder unauthorized charges are to spot.
What crammed charges look like
The FCC lists these warning signs:
- Vague descriptions such as "service fee," "service charge," "other fees," "voicemail," "mail server," "calling plan" or "membership."
- Recurring charges with no clear explanation, like a "monthly fee" or "minimum monthly usage fee."
- Services you didn't authorize, such as ringtones, wallpaper or "premium" text subscriptions (sports scores, horoscopes and the like).
Crammed charges are often tiny, sometimes only $1, $2 or $3, spread across thousands of customers, and the FCC says they can stay on bills for years.
How to check your bill each month
The FCC suggests reviewing your phone bill as closely as a bank or credit card statement and asking:
- Do I recognize the names of all the companies on the bill?
- What service did each company provide?
- Are there charges for calls I didn't make or services I didn't authorize?
- Do the rates and line items match what I was quoted?
If a charge is unclear, ask your phone company to explain it before paying. Keep a record of services you've authorized, and read the fine print before signing up for anything billed to your phone.
Your Truth in Billing rights
FCC Truth in Billing rules require phone companies to:
- Describe billed services in clear, plain language.
- Identify the provider behind each charge.
- Say which charges could get basic local service disconnected if unpaid, and which couldn't.
- Show one or more toll-free numbers for questions and disputes.
Wireline (landline) companies must also tell you about any blocking options for third-party charges, put third-party charges in a separate section of the bill, and give them their own subtotal. If you never want outside companies billing through your landline, ask about that block.
Charges that are normally legitimate
Not every unfamiliar line is cramming. The FCC's guide explains several common items:
| Line item | What it is, per the FCC |
|---|---|
| Access charges (e.g. "Federal Access Charge," "Subscriber Line Charge") | Local phone companies recovering part of the cost of their local network; not a government tax. The FCC sets the maximum. |
| Federal excise tax | A 3% tax that applies only to local service billed separately from long distance. |
| State and local taxes | Taxes set by state and local governments, sometimes shown as "gross receipts" taxes. |
| Universal service | Carriers may pass their Universal Service Fund contributions on to you, usually as a percentage of the bill; the FCC doesn't require it. |
| 911, LNP and TRS charges | 911 fees help local governments pay for emergency services; local number portability (LNP) fees cover keeping your number when you switch (not taxes; some companies charge none); relay service fees help pay for calls for people with hearing or speech disabilities. |
If you're not sure whether a line is a normal fee or a third-party charge, ask the carrier which company it's for.
If you've been crammed
- Call the phone company that sends the bill, explain the problem and ask to have incorrect charges removed.
- You can also call the company that charged you and ask for an explanation and an adjustment.
- If neither removes it, file a complaint:
- with the FCC about charges on your phone bill,
- with your state public service commission for phone service within your state, or
- with the Federal Trade Commission for charges for non-telephone services billed to your phone.
The FCC says complaints matter: in 2014 and 2015, federal and state regulators took action against the four largest wireless companies over unauthorized premium text charges, which led to $353 million in penalties and restitution.
