Telecom Cramming Charges on Phone Bills
How unauthorised third-party charges for subscriptions and services are added to phone bills without the customer's genuine consent.
Part of: Telecom Cramming Charges Scams
Last reviewed: 8 June 2026
Cramming is the practice of placing unauthorised or misleading charges on telephone bills for services the customer did not knowingly order. Third-party service providers — ringtone services, horoscope subscriptions, premium SMS clubs — place charges on phone bills through carrier billing arrangements, and many customers never notice because phone bills are not scrutinised line by line.
The charges typically range from a few pounds or dollars per month, and the service names on the bill are often obscure. Customers who signed up for a free trial through an SMS keyword, clicked an ad, or entered a competition may have inadvertently authorised a recurring charge buried in the terms.
How this scam works on phone bills
A consumer sends an SMS keyword in response to an ad, enters a competition, or clicks a banner for a free ringtone or horoscope. The terms, in small print, authorise recurring charges to their phone bill. Monthly charges of a few pounds or dollars appear under an unfamiliar service name on subsequent bills.
When the consumer attempts to cancel, they must contact the third-party service — whose contact details may be difficult to find. Some carriers allow customers to block third-party billing entirely, but many consumers are unaware this option exists.
Common red flags
- Phone bill includes line items from service names you do not recognise
- Small recurring charges appear after sending an SMS keyword or entering a competition
- Charges are labelled as third-party services rather than your carrier's own products
- The amount charged increases gradually across multiple months
- You cannot identify the service associated with a charge despite investigating
How to protect yourself
- Review your phone bill in detail each month and query any line you cannot identify
- Ask your carrier to block all third-party billing on your account
- Avoid sending SMS keywords to shortcode numbers in unsolicited ads
- Screenshot all competition entries and free-trial sign-ups that involve your phone number
- Contact the third-party service directly to cancel and ask your carrier to reverse the charges
How to report it
- Report to your national telecom regulator (Ofcom UK, FCC US)
- Report to the FTC at reportfraud.ftc.gov (US) for cramming violations
- Ask your carrier to raise a billing dispute and refund the unauthorised charges
Frequently asked questions
Will asking my carrier to block third-party billing affect any services I actually use?
It can block legitimate premium services too, such as charity donations by text or certain paid content subscriptions, so ask your carrier specifically what will and won't be affected before requesting a full block.
How far back can I typically get cramming charges refunded?
This depends on your carrier's policy and your jurisdiction's regulations — ask your carrier directly what their refund window is when you raise the dispute, and provide as much detail as possible about when you first noticed the charge.
Can my carrier remove third-party billing charges from my account?
Yes. Most major carriers will investigate and credit clearly unauthorised third-party charges upon request. You can also ask for a permanent block on all third-party billing to prevent future cramming.
