What TCR Error 3104 Means
TCR error code 3104 indicates T-Mobile has rejected your campaign due to content policy violations detected in submitted sample messages. T-Mobile enforces the strictest content filtering among U.S. carriers through their SHAFT policy framework, which prohibits messaging related to sex, hate speech, alcohol, firearms, and tobacco.
T-Mobile Content Policy Violation
T-Mobile Only
Blocked on T-Mobile Network
Why This Error Occurs
T-Mobile's automated content analysis systems scan all submitted sample messages during campaign registration. The carrier's filtering algorithms detect prohibited content categories, trigger error 3104, and block campaign deployment on their network. This error is carrier-specific and does not prevent approval on AT&T or Verizon networks.
SHAFT Content
References to sex, hate speech, alcohol, firearms, or tobacco in any message context trigger immediate rejection.
Crypto Promotion
Cryptocurrency, NFT, or blockchain product marketing violates T-Mobile acceptable use policies.
Phishing Simulation
Security awareness training messages mimicking phishing attacks are classified as deceptive content.

-
1
Identify Prohibited Content Categories
Review all submitted sample messages against T-Mobile's SHAFT framework. Violations include direct references, euphemisms, and contextual implications related to prohibited categories. Cannabis, alcohol brand names, firearm mentions, and adult content all trigger error 3104.
Technical Detail: T-Mobile employs natural language processing algorithms detecting prohibited keywords across 47 languages. Common triggers include "beer," "wine," "spirits," "cigar," "vape," "gun," "ammo," and cannabis-adjacent terminology. -
2
Remove Violating Content From Message Templates
Eliminate all references to SHAFT categories from approved sample messages. Organizations cannot circumvent detection through misspellings, special characters, or obfuscation techniques. T-Mobile's content filters evaluate semantic meaning rather than exact keyword matching.
Technical Detail: Compliant alternatives require complete content pivot. Alcohol distributors must rebrand as "beverage companies," firearms retailers as "sporting goods," and cannabis operations cannot reference product categories under any messaging use case. -
3
Submit Compliant Sample Messages
Update campaign registration with T-Mobile-approved message content. Sample messages should demonstrate business purpose without referencing prohibited categories. Transactional use cases (order confirmations, shipping notifications) receive higher approval likelihood than promotional messaging.
Technical Detail: Submit 3-5 representative message samples covering use case breadth. Include opt-in confirmation, informational notification, and promotional examples when applicable. Avoid edge cases that may trigger secondary content review. -
4
Await T-Mobile Automated Review
T-Mobile processes corrected campaign submissions through automated content analysis within 24-48 hours. Campaigns passing content filters proceed to trust score evaluation and network deployment. Organizations may monitor approval status through CSP dashboards or TCR portal.
Technical Detail: Content-only corrections typically clear automated review without manual intervention. Campaigns requiring use case changes or brand modifications may trigger extended 3-5 business day review timelines pending carrier verification.

Fix Your CampaignTechnical Requirements
TCR error 3104 violations stem from T-Mobile's implementation of CTIA Messaging Principles and Best Practices regarding prohibited content categories. The carrier maintains zero-tolerance policies for SHAFT content regardless of business model, use case category, or message volume.
T-Mobile SHAFT Policy Framework
T-Mobile enforces content restrictions across five prohibited categories under their SHAFT framework. Organizations submitting campaigns containing references to sex, hate speech, alcohol, firearms, or tobacco face immediate network-level blocking through error 3104. The carrier's content filtering systems employ machine learning algorithms trained on multilingual datasets covering 47 languages and regional dialects.
Prohibited Content Categories:
- Sex: Adult entertainment, dating services, sexual wellness products, explicit content
- Hate: Discriminatory messaging, extremist content, harassment, targeted abuse
- Alcohol: Beer, wine, spirits brands, liquor promotions, bar/brewery marketing
- Firearms: Gun sales, ammunition, tactical equipment, shooting sports
- Tobacco: Cigarettes, cigars, vaping products, nicotine delivery systems
Additional T-Mobile Content Restrictions
Beyond SHAFT categories, T-Mobile prohibits cryptocurrency promotion, phishing simulation messages, and cannabis-related content. Organizations operating in these verticals cannot deploy campaigns on T-Mobile's network regardless of legal status in operating jurisdictions. Error 3104 blocks campaigns immediately upon content detection without appeal process.
Carrier-Specific Enforcement Variations
Error 3104 is T-Mobile exclusive. AT&T and Verizon enforce different content policies with varying restriction scopes. Campaigns rejected by T-Mobile for SHAFT violations may receive approval on competing carrier networks. Organizations requiring T-Mobile distribution must remove prohibited content entirely rather than pursuing multi-carrier selective deployment strategies.
Prevention Strategy
Organizations avoiding TCR error 3104 implement proactive content controls during campaign development and message template creation. Pre-submission validation identifies T-Mobile prohibited content before carrier review processes.
Pre-Submission Content Validation
Validate all sample messages through automated content analysis tools before TCR submission. MyTCRPlus SMS Message Validator identifies SHAFT violations and provides T-Mobile-compliant alternatives.
Message Template Libraries
Maintain carrier-approved message template libraries organized by use case category. Version control ensures message content remains compliant as T-Mobile policies evolve.
Compliance Training Protocols
Train marketing teams on T-Mobile content restrictions before granting campaign creation access. Regular policy updates prevent inadvertent SHAFT violations during message authoring.
