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

Based on your Trust Score T-Mobile limits the amount of messages you can send to their subscribers.

Updated over a week ago

Under the new 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 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 Brand can send toward T-Mobile (incl. Sprint) subscribers per day.

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

Update: As of September 14, 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).

The limit 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.

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 an error stating that you have reached your daily message cap for 10DLC on T-Mobile. This daily limit will reset on the next calendar day.

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

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