Fake T-Mobile Premium SMS Subscription Scam
Scammers use third-party billing to add unauthorised premium SMS subscription charges to T-Mobile bills, or send fake T-Mobile messages luring customers into inadvertently subscribing.

Last reviewed: 7 June 2026
Premium SMS services — which charge a fee each time a customer sends or receives a message from a specific shortcode — can legitimately appear on mobile bills. However, unscrupulous operators exploit the T-Mobile billing system to enrol customers without meaningful consent, or use deceptive advertisements and text messages to lure customers into triggering a subscription.
A single text reply to a seemingly innocuous promotional message can activate a recurring daily or weekly subscription billed to the customer's T-Mobile account at rates that may not be obvious until the next bill arrives. T-Mobile is the billing intermediary in these cases — it collects the charges on behalf of the third-party content provider.
A distinct scam sends messages that appear to come from T-Mobile itself, claiming the customer has been enrolled in a premium service and must text 'STOP' to avoid charges. Responding to this message can itself trigger a new subscription.
How this scam works on the T-Mobile brand
Fake premium SMS subscriptions are often triggered by clicking a banner ad on a mobile site that loads the billing opt-in behind the scenes. The consumer sees only an ad or a prize claim page, while the billing request is submitted automatically. The first sign of a problem may be a line item on the monthly T-Mobile bill labelled with an unfamiliar company name and a recurring weekly charge.
The fake T-Mobile message variant arrives as a text appearing to come from a T-Mobile shortcode. It claims: 'You have been enrolled in [Service Name] at $X/week. Reply STOP to cancel.' Replying STOP to this message can actually enrol the customer in a real subscription managed by the fraudulent service, because the act of replying constitutes a billing consent in some systems.
T-Mobile's genuine billing alerts come from recognised T-Mobile shortcodes and are always visible in the T-Mobile app under billing details. T-Mobile does not ask customers to text STOP to an unknown shortcode to avoid charges from an enrolment they did not initiate.
Common red flags
- A text claiming you have been enrolled in a premium service that you do not recognise
- A small weekly or daily charge from an unfamiliar company name appearing on your T-Mobile bill
- A mobile ad that asks you to enter your phone number to 'enter a draw' — this can trigger a billing subscription
- The 'STOP' instruction leads to a shortcode you have no history with, and replying generates a confirmation message
- Clicking a banner ad while on the T-Mobile mobile network triggers a subscription without a clear confirmation step
How to protect yourself
- Request a premium SMS block from T-Mobile by calling 611 or through the My T-Mobile app — this prevents all premium shortcode billing
- Review your T-Mobile bill monthly and challenge any charges from unfamiliar third parties
- Never reply to unsolicited texts claiming you have been enrolled in a service — contact T-Mobile at 611 to verify the charge and block the service
- Avoid entering your phone number in mobile ads or prize-entry forms unless you fully understand the billing terms
How to report it
- Report the charge to T-Mobile at 611 and request a refund and a premium SMS block
- File a complaint with the FCC at consumercomplaints.fcc.gov
- Report to the FTC at reportfraud.ftc.gov
- If the charge is substantial and unresolved by T-Mobile, escalate to your state attorney general's consumer protection office
Frequently asked questions
Can T-Mobile remove premium SMS charges I did not authorise?
Yes. T-Mobile will typically remove charges from third-party services you did not knowingly subscribe to. Call 611, explain the charges, and request both a refund and a premium SMS block on your account.
Is it safe to text STOP to cancel a subscription I do not recognise?
Not always. Replying to an unknown shortcode can in some cases activate a new subscription. Instead of replying, contact T-Mobile at 611 to block and refund the service without interacting with the shortcode.
