T-Mobile Special Business Review for A2P 10DLC

Under A2P 10DLC, T-Mobile (including Sprint) is imposing daily message limits. This sets a total number of outbound SMS segments and MMS messages that your registered A2P Brand can send toward T-Mobile (and Sprint) subscribers per day. For details, see T-Mobile daily message limits for long code messaging with A2P 10DLC.

Customers who need the ability to send more than 200,000 daily SMS segments and MMS to T-Mobile must follow the below procedure to submit T-Mobile Special Business Review (SBR) requests. ISVs who have clients with this messaging volume requirement must submit the SBR on behalf of their client. Please download and complete this Twilio SBR Submissions template. Additional guidance, including specifics on each field in the template, is below. If you have further questions about the T-Mobile SBR process, please reach out to 10dlc-onboarding@twilio.com
