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.

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.

How can I avoid exceeding my T-Mobile daily message limit?

To avoid exceeding your daily limit, make sure you are monitoring your daily T-Mobile usage. This can be done using Messaging Insights from the console. To view your daily T-Mobile message limit, please visit Trust Hub - A2P Messaging , select your US A2P brand, and view the details of your TCR trust score (registered customers only). Finally, you can also use the  30025, 30026 ‘Daily Traffic Used’ error warnings to monitor what percentage of your daily traffic has been used. The ‘Daily Traffic Used’ error codes and ‘Daily Traffic Exceeded’ error warnings are available in the console debugger. Please keep in mind that, the daily T-Mobile limit applied to all registered Brands associated with your EIN, so when monitoring your daily usage, you would need to do this across all Brands, whether they are in the same account, multiple accounts, or multiple providers.
