What is a T-Mobile "Special Business Review"?


In addition to Brand Registration, Use Cases, and Campaign Verify tokens for political organizations, T-Mobile has additional compliance measures for high-volume texters to receive an exemption from their daily message limits. These are submitted separately to Twilio and Bandwidth. If your messaging volume approaches 250K messages for any single day we highly recommend completing this process once it becomes possible, to ensure that all of your messages are sent. 


At some point, the Special Business Review will require a one-time fee of $5,000. However, T-Mobile recently announced that they have delayed that fee indefinitely.  


It's important to note that you will not be able to submit a Special Business Review request until you've completed your Brand & Use Case Registration in ThruText, which generates the TCR Campaign ID needed to fill out the form.


Do I need a T-Mobile Special Business Review?


Probably not. T-Mobile has established a maximum limit of 200,000 message segments per day to T-mobile subscribers. If you plan to send more than 250,000 total messages from a single ThruText account on any one day, we recommend that you complete a Special Business Review. 


Here's a look into the calculus we used to arrive at that estimate: On average, T-Mobile subscribers will comprise around 25% of your contacts and typical messages average 3 message segments, ergo: 200K total daily segments divided by 3 segments per message = 67K messages per day X 4 (25% of your contacts) = 250K (with a small safety margin) total messages per day to meet the threshold for requiring an SBR.
