The 10DLC carrier landscape

The text discusses the differences in how Verizon, AT&T, and T-Mobile handle their 10DLC launches. Verizon has a surcharge that applies to both SMS and MMS traffic with no special requirements for registration. On the other hand, AT&T and T-Mobile use The Campaign Registry (TCR) in slightly different ways. AT&T assigns message-per-second limits at the campaign level based on proprietary information from TCR, while T-Mobile sets daily limits on messages sent to their customers based on Brand scores during registration.
