T-Mobile's A2P messaging guidelines

T-Mobile, along with other carriers, aims to create a safe and reliable mobile experience for their customers. This includes protecting them from unwanted and potentially harmful text messages. By enforcing existing regulations more diligently, they hope to minimize spam and ensure a positive texting environment for everyone.

They are actively monitoring A2P outbound SMS and MMS messaging to USA numbers.

T-Mobile has introduced A2P 10DLC non-compliance fines for messages including prohibited content. If T-Mobile detects any messages that violate the tiers listed below, they will issue a Sev-0 violation (the most severe consumer violation), a non-compliance fine.  

Applies to all three messaging types: including 10DLC, toll-free numbers, and short code.

Our messaging provider, Twilio, also adheres to specific A2P compliance regulations. In the very unlikely event that Twilio incurs any fines from T-Mobile associated with your business account due to non-compliance, Referrizer will pass those fines on to you. These fines include, but are not limited to, the following:

  • Tier 1: $2,000: phishing (including simulated phishing sent for security testing or similar purposes), smishing, and social engineering. Social Engineering is a technique used to manipulate someone into sharing private information, like passwords or credit card numbers.
  • Tier 2: $1,000: illegal content (content must be legal federally and in all 50 states).
  • Tier 3: $500: all other violations in commercial messaging including but not limited to, SHAFT (sex, hate, alcohol, firearms, and tobacco) that do not follow federal and state law and regulations.

Remember: By adhering to responsible A2P messaging practices, you not only avoid potential fines but also ensure a positive experience for your audience and contribute to a healthier mobile ecosystem.

For clarity: This update targets Application-to-Person (A2P) / commercial messaging used by businesses to reach their customers. Your personal text messages sent to friends and family are not affected.
