| MMS, Trust Score 75+, per carrier | Up to 40 MPS |
From 18 March 2026, Twilio sets the MMS rate limit for 10DLC numbers by Brand Trust Score and campaign use case. A brand with a Trust Score of 75 or more can send up to 40 MMS per second to each of AT&T, T-Mobile and Verizon.
Sole proprietor brands get a fixed limit. The Trust Score comes from brand vetting. A brand with a low score can ask for secondary vetting to get a higher score.
