Dynamic queue technology — included free

Every carrier meters traffic differently: daily brand limits at T-Mobile, per-minute limits by class of service at AT&T. Tychron's dynamic queue absorbs your bursts and paces them into each carrier's exact limits in real time — so messages are delivered at the highest rate every network allows instead of being blocked at a cap. No extra work, no extra cost.

10DLC questions, answered

How long does 10DLC registration take?

Most campaigns approve in 24–72 hours when submitted correctly. The full requirements, fees, and rejection reasons are in our 10DLC Registration Guide.

What does 10DLC cost?

TCR charges a one-time brand fee ($4.50) plus a monthly campaign fee ($1.50–$30 by type), and carriers add per-message pass-through fees — current 2026 tables are on our registration page. Tychron passes registry and carrier fees through at cost, and dynamic queue throughput management is included free.

What throughput will my campaigns get?

Carrier limits work differently network by network — T-Mobile sets daily brand limits, while AT&T meters per minute based on class of service. Tychron's dynamic queue paces your traffic into each carrier's exact limits in real time, so nothing is blocked for exceeding a cap and you deliver at the highest rate every carrier allows. Queuing is included free.

Can I manage 10DLC programmatically?

Yes. Beyond the Atlas portal, Tychron’s API covers the full lifecycle: order numbers, register brands and campaigns with TCR, assign numbers to campaigns, sync opt-out lists, and subscribe to webhook events when registrations complete.
