What is T-Mobile’s 7728 (SPAM) Short Code?

The number 7728 was chosen because it spells SPAM on a phone’s keypad, making it easy to remember. It is the industry-standard reporting system that T-Mobile fully supports to help keep its network clean.

  • Purpose: To serve as a dedicated inbox for T-Mobile’s security team to receive and analyze spam, phishing (“smishing”), and other malicious text messages reported by customers.
  • Cost: This is a completely free service. T-Mobile does not charge you for forwarding messages to this number, and it does not count against any message limits on your plan.
  • Goal: To gather real-time data on spam campaigns, allowing T-Mobile to block fraudulent numbers, shut down scammers, and improve the effectiveness of network-level filters like Scam Shield.

How to Use the 7728 Short Code on T-Mobile (Step-by-Step)

Reporting a spam text on the T-Mobile network is a quick and simple process. The steps are nearly identical for both iPhone and Android devices.

  1. Do NOT reply to the spam message. Never click on any links or call any numbers in a suspicious text. Interacting with the message confirms to the scammer that your number is active.
  2. Press and hold the spam message bubble until a menu of options appears.
  3. Select the “Forward” (On some Android phones, you may need to tap a three-dot menu icon first and then select “Forward”).
  4. A new text message will be created with the spam content copied into it. In the “To:” recipient field, type the four-digit number 7728.
  5. Press Send.

You have now successfully reported the spam message to T-Mobile.

What Happens After You Report a Message to T-Mobile?

Once you have forwarded the spam text, your report is sent directly to T-Mobile’s anti-abuse and security department.

  • You’ll Receive a Confirmation: In most cases, you will get an immediate automated text back from T-Mobile thanking you for the report.
  • T-Mobile Investigates: The security team analyzes the message’s content, links, and origin number. This information is used to identify the source of the spam.
  • The Network is Protected: Using the data from your report, T-Mobile can block the spammer’s number at the network level and update its Scam Shield technology to better detect similar threats in the future.

While reporting one message won’t stop all spam, your report contributes to a larger effort that makes the mobile network safer for all T-Mobile customers. For immediate relief, it is also recommended that you manually block the sender’s number on your phone after reporting it.
