T-Mobile daily message limits for long code messaging with A2P 10DLC

Under the new A2P 10DLC service for sending messages via 10-digit long code numbers in the United States, there are changes to how message sending capacity is allocated. Message sending throughput (MPS) is changing and will be based on your Trust Score, as described in Message throughput (MPS) and Trust Scores for A2P 10DLC in the US.

In addition, T-Mobile (including Sprint) is imposing daily message limits based on your Trust Score. This sets a total number of outbound SMS segments and MMS messages that your registered A2P Brand can send toward T-Mobile (incl. Sprint) subscribers per day.

Default daily message limits for T-Mobile (incl. Sprint) under A2P 10DLC

Update: As of July 22, 2021, Twilio is changing Brand registration to include automatic secondary vetting. This will ensure that your Brand receives the highest possible daily message cap to T-Mobile.

You will receive a T-Mobile daily message cap based on your Trust Score (secondary vetting score). This limit is applied at the A2P Brand level, and shared among all Campaign use cases under that Brand.

The limit is applied at the Brand level and is based on the total number of outbound SMS segments and MMS messages sent to T-Mobile (including Sprint and MetroPCS).

The only exception by default is businesses that are in the Russell 3000 Index, who will receive a total limit of 200,000 SMS segments and MMS per day toward T-Mobile by default.

How will these limits affect me?

First, please note: As of July 2021, T-Mobile traffic enablement is not instant and automatic when you complete Brand and Campaign registration. This means that once you are invited and complete registration, you will have time to assess your Trust Score and other factors before any message traffic is affected by T-Mobile's daily limits. For details, see What is A2P 10DLC and Limitations of A2P 10DLC pilot access.

What will happen if I exceed my T-Mobile daily message limit?

If you exceed your T-Mobile daily message limit your messages will be undelivered with a 30023 error stating that you have reached your daily message cap for A2P 10DLC on T-Mobile. This daily limit will reset on the next calendar day.

T-Mobile daily message limits based on Trust Score

The limits that T-Mobile will offer based on your Trust Score (after secondary vetting) are shown below.

51-75

40,000/day

How can I get a limit higher than 200,000 messages per day toward T-Mobile?

T-Mobile only removes the cap of 200,000 SMS segments + MMS per day if a business completes a process called Special Business Review. For more information on Special Business Review and details on how to submit a request, please see T-Mobile Special Business Review for A2P 10DLC.
