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

Article contents:

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

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 (per EIN) 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.

Please note, these limits are applied by T-Mobile at your Brand level, and are shared if you are registered on multiple different messaging platforms or services. For example, if Owl Company is registered with their own Twilio account, and also registered for A2P 10DLC messaging through a 3rd party support software called OwlDesk, then the Brand-level limit for Owl Company will be shared across both registrations and platforms.

How will these limits affect me?

First, please note: As of February 2022, 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 Current limitations of A2P 10DLC.

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 (Pacific US Time). 

What time does the T-Mobile daily limit reset every day?

The daily limit resets every day at midnight, Pacific US Time.

T-Mobile daily limit for Sole Proprietor brands

There is a limit of 1,000 message segments per day for Sole Proprietor brands.

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. 

What happens if I choose to opt-out of Secondary Vetting for my clients' Brands?

You have the option to selectively opt-out of Secondary Vetting for your clients' Brand registrations. However, be aware that any Brand that does not receive Secondary Vetting will be subject to the following restrictions.
