The short code 2941 is a legitimate, verified SMS number used by T-Mobile (and previously Sprint, due to the merger) to send critical, non-marketing alerts to customers. Its primary function is to confirm technical actions taken on your account, most notably the completion of a SIM card swap or device activation.
If you receive a text message from the 2941 short code that you weren’t expecting—especially one mentioning a SIM change—you should treat it as a potential security risk and verify your account status immediately, as these messages are a known component of SIM swap scams. This article will break down the purpose of the 2941 short code, what to do if you receive an unexpected text from it, and provide steps to secure your mobile account.
What is the 2941 Short Code Used For?
Short codes are typically 5 or 6-digit numbers used by large companies for mass texting, two-factor authentication (2FA), and system alerts. The 2941 short code is primarily used by T-Mobile to confirm security and account management actions.
- SIM Card Swap and Activation Confirmation
The most documented use of the 2941 short code is to send automatic confirmation notices related to a SIM change or network migration (like the transition of old Sprint customers to the T-Mobile network, known as the TNX process).
A typical message from 2941 might read:
“Success! Your SIM swap is complete. Restart your phone to see our new network in action.”
If you recently completed a SIM card swap, device activation, or a major change to your cellular service, this text is simply a confirmation of that action.
- General Account Security Alerts
While T-Mobile uses other short codes (like 456) for a variety of account changes, 2941 is considered an official T-Mobile channel and may also be used for other critical, non-promotional security alerts regarding your line or device.
| Short Code | Carrier | Primary Purpose |
| 2941 | T-Mobile/Sprint | SIM Swap/Device Activation and critical network notifications. |
| 7726 | Universal | Report spam texts (by forwarding the message to this number). |
| 456 | T-Mobile | General account alerts (PIN/Password change, AutoPay). |
🚨 Security Alert: What to Do If the Text is Unexpected
Receiving an unsolicited message from the 2941 short code text message can be a major red flag for an attempted SIM swap attack. In this fraud scheme, a hacker tries to convince the carrier (T-Mobile) to transfer your phone number to their device (using a new SIM card).
If you receive a 2941 text confirming a SIM swap that you did not initiate, take these steps immediately:
- Do NOT Restart Your Phone: A SIM swap attack is successful when the new SIM is activated, which often requires a phone restart. If your phone still has service, do not restart it.
- Contact T-Mobile Security IMMEDIATELY: Use a different phone (a landline or a friend’s phone) and call T-Mobile’s fraud department directly.
- T-Mobile Customer Care: Dial 611 from your phone (if service is active) or 1-800-937-8997.
- State clearly that you received an unauthorized SIM swap notification. The representative can place an immediate lock on your line to prevent the change.
- Change Your PIN/Password: Log into your T-Mobile account online and immediately change your Account PIN and your My T-Mobile password. Use a strong, unique, alphanumeric password.
- Check Other Accounts: Once a number is ported, hackers gain access to 2FA codes. Check your bank, email, and social media accounts for any suspicious login attempts.
How to Stop Unwanted Texts from Short Code 2941
If the messages from 2941 are recurring and unwanted promotional spam (which is less common for this specific code, but possible), you can usually opt out using industry-standard keywords.
Method 1: Reply with STOP (Standard Opt-Out)
Most legitimate short codes are legally required to accept “STOP” requests.
- Open the text conversation with the number 2941.
- Reply simply with the word STOP (case does not usually matter).
- Wait for a confirmation message stating that you have been unsubscribed. If you receive a confirmation, you should not receive further messages.
Method 2: Report as Spam
If the messages persist or appear to be fraudulent, report them to your carrier:
- Forward the entire original text message to the universal carrier spam reporting short code: 7726 (SPAM).
- You will be asked to reply with the original sender’s number (in this case, 2941). T-Mobile will then investigate the sender for potential abuse or scam activity.
Frequently Asked Questions (FAQ)
Is 2941 a 4-digit or 5-digit short code?
The 2941 short code is a four-digit short code. While many short codes are five or six digits, four-digit numbers are still used for certain specific services, particularly internal carrier alerts. The four-digit length does not indicate whether it is legitimate or a scam.
Should I click a link in a text message from 2941?
Only click a link if the message is expected and the domain is official. If the 2941 text contains a link and you did not initiate the process, do not click it. Legitimate T-Mobile links often use the verified t-mo.co domain. If the link is shortened, scrambled, or leads to an unfamiliar website, assume it is a phishing attempt.
Can I block the 2941 short code?
You can technically block any number using your phone’s native messaging app settings (Android or iPhone). However, since 2941 is used for legitimate, important T-Mobile alerts (like SIM change confirmations), blocking it is generally not recommended, as you might miss a critical security notification in the future. It is better to use the “STOP” method if the messages are unwanted promotional spam.
What is the difference between an Account PIN and a SIM Swap?
Your Account PIN/Passcode is a 6-15 digit number used to verify your identity when calling T-Mobile or accessing your account. A SIM Swap is the act of physically moving your phone number from one SIM card to another. Hackers need your PIN to authorize a SIM Swap, which is why a notification from 2941 about an unauthorized swap is a sign that your PIN may have been compromised.
Conclusion
The 2941 short code text message is an official, legitimate channel used by T-Mobile primarily for confirmation of security-related actions like a SIM card swap. If you receive a text from 2941 that aligns with a recent account action you took, it is harmless. If you receive a text from 2941 unexpectedly, act fast: treat it as a potential SIM swap attempt, contact T-Mobile customer service immediately using a different line, and change your account security credentials to prevent fraud.
