10DLC - New Violation Fines 

• Beginning  January 1, 2024, T-Mobile is instituting three new fees for non-compliant traffic that result in a Severity-0 violation. A  Sev-0 (Severity-0) represents the most harmful violation to consumers and applies to all products (SMS or MMS, Toll-Free, and 10DLC) that transverse T-Mobile's network. 
• The non-compliance fine(s) (USD) will be assessed for every Sev-0 violation issued as follows: 
  
  • Tier 1: $2,000 for phishing, smishing, and social engineering 
    
    • 'Social Engineering' refers to the practice of targeting individuals in a way that manipulates individuals to reveal private information like credit card numbers or social security numbers. 
  • Tier 2: $1,000 for illegal content (included content must be legal in all 50 states and federally legal). 
    
    • Illegal content includes, but is not limited to, Cannabis, Marijuana, CBD, Illegal Prescriptions, and Solicitation. 
  • Tier 3: $500 for all other violations including, but not limited to, SHAFT (sex, hate, alcohol, firearms, and tobacco) content.  
• If traffic continues to receive Sev-0 violations, carriers maintain the right to suspend a brand, remove access to their platforms, and may also block all messaging traffic. Therefore, you must ensure that all traffic leaving your network is wanted and compliant.

10DLC – Message Blocking on the Rise 

At this time of year, our industry typically sees higher volumes of traffic, and we have already seen cases where messages that do not meet current messaging standards are being blocked. 

To avoid any potential blocking, ensure your campaigns are fully compliant. Use the requirements outlined below and in our 10DLC Key Attributes to Get Your SMS Campaign Approved

Active campaigns should meet the following requirements: 

• The content being sent: 
  
  • Matches what was described during the campaign registration process. *Most small business clients' use case falls within Low Volume Mix - Customer Service
  • Is not considered prohibited content.
• The campaigns collect proper opt-in. 
  
  • The SMS Disclosure must be plainly visible either next to the phone number field or above the submission button on the contact web form.
    
  • If there are multiple contact web forms with a field to input a phone number, the SMS Disclosure must be plainly visible on each contact web form.
  • A link to the privacy policy is included in the contact web form SMS Disclosure statement. 
  • The privacy policy does not commit to selling/sharing personal information with third parties. 
• The campaigns are compliant with current messaging best practices.
  
  • All campaigns must contain a message flow or call to action. 
    
  • This is configured within the Campaign when it is registered. Ex: Reply HELP for help, and STOP to unsubscribe.
