Carrier Throughput Estimator

Estimate your sending capacity across the three major carriers from your Trust Score band, campaign count, and number count — because T-Mobile, AT&T, and Verizon each allocate throughput differently.

The three carriers do not share a throughput model. T-Mobile caps a daily segment count per brand (shared across all campaigns and numbers). AT&T allocates a per-minute rate per campaign. Verizon is fixed per number. Pick your Trust Score band and counts to see all three.

T-Mobile, AT&T, and Verizon capacity from your Trust Score

Raises AT&T capacity (per-campaign), not T-Mobile.
Raises Verizon capacity (per-number).
  • Pay for external/secondary vetting to raise your Trust Score — the biggest lever for T-Mobile and AT&T.
  • Use an Aegis Enhanced vet if the standard score is unsatisfactory.
  • Choose the highest-throughput legitimate use case (e.g. AT&T Social class).
  • Split traffic across campaigns — helps AT&T (per-campaign), not T-Mobile's brand-wide cap.
  • Add numbers / a Number Pool — helps Verizon and spreads AT&T; not T-Mobile's daily cap.
  • Apply for T-Mobile Special Business Review to exceed 200,000/day.
Planning estimates. T-Mobile is a brand-wide daily cap (shared); AT&T is per-campaign TPM; Verizon is per-number and aggregator-reported. Your CSP's enforced limits and actual carrier mix govern real delivery.

How it works

  • T-Mobile — a brand-wide daily cap keyed to your Trust Score band. It is not multiplied by campaigns or numbers; splitting traffic does not raise it.
  • AT&T — a per-campaign TPM (messages per minute) for your band. Effective capacity is the per-campaign rate × your number of campaigns, since AT&T allocates separately per campaign.
  • Verizon — a fixed ~6,000 SMS TPM per sending number, independent of Trust Score. Adding numbers adds capacity (~4,500 TPM ≈ 75 MPS for reference).

Caveats

Verizon figures are aggregator-reported; Verizon does not officially publish them. The Sole Proprietor path has no Trust Score and fixed low throughput. These are planning estimates — your CSP’s enforced limits and your actual carrier traffic mix govern real delivery.
