Messaging on carrier rates. Not CPaaS rates.
REST API for SMS and MMS. A2P 10DLC campaign + brand registration done for you. Toll-free SMS on request. Billed per segment — no marketing-tier pricing gates, no message-volume minimums.
Everything an A2P program needs. At carrier rates.
Contact center reminders, OTPs, two-way support, marketing opt-in flows — the same API covers all of them. We register the 10DLC campaign; you send messages.
A2P 10DLC registration
Brand and campaign registered with TCR. We file the vetting docs on your behalf, maintain the trust-score, and keep you in good standing with the mobile carriers.
Toll-free SMS
800/833/844/855/866/877/888 prefixes, SMS-enabled. Responsible-organization filing included. Higher throughput than 10DLC for non-marketing use cases.
Two-way messaging
Inbound replies land as webhook POSTs or are pulled via REST. Opt-out keywords (STOP/UNSUBSCRIBE) handled automatically per CTIA.
MMS
Images, vCards, short audio. Same API endpoint — add a media URL and the segment math updates.
One rate per segment. Same across your whole account.
| Message type | Per segment (outbound) | Per segment (inbound) | Monthly number fee |
|---|---|---|---|
| A2P 10DLC · SMS | $0.0065 | $0.0050 | $5 (same as voice DID) |
| A2P 10DLC · MMS | $0.0180 | $0.0090 | included |
| Toll-free · SMS | $0.0075 | $0.0050 | $10 (same as voice TF) |
| Toll-free · MMS | $0.0200 | $0.0100 | included |
POST /v1/messages. Done.
Port the 10DLC campaign too. We handle TCR re-assignment.
Your campaign registration stays intact — brand, use case, trust score. We move the ownership on TCR so nothing breaks in production.
