Providers & Platforms
The CSP / CPaaS landscape for 10DLC registration, plus the utility tools — lookups, policy generators, deliverability monitoring — that brands actually use.
All CSPs route to the same Campaign Registry — they differ in markup, sole-proprietor support, and self-service vs managed UX. Pick by how much hand-holding and how many sub-brands you need, not by registry price (the TCR fees are identical).
CSP / CPaaS comparison
| Provider | Brand reg | Campaign vet | Sole prop | Notable |
|---|---|---|---|---|
| Telnyx | $4.50 | $15 | Yes | Passes TCR/carrier fees at cost (no markup); monthly campaign $1.50–$10. |
| Twilio | TCR fees + own per-campaign fees | $15 | Yes | Full self-service console + API; Messaging Service container model; Low-Volume Standard path. |
| Bandwidth | $4 | $15 / vetting event | No | Tier-1 carrier/DCA; can register as own CSP ($200); T-Mobile NNID $2,000; billing on rejected + approved submissions. |
| Plivo | $4-tier | — | — | Authentication+ $12.50. |
| Vonage | Resells via CSP model | — | — | Reseller vs CSP distinction. |
| Sinch | Resells via CSP model | — | — | Bundles carrier surcharges into one all-in rate. |
| Bird (ex-MessageBird) | ~$4–44 | — | — | ~$10/mo per campaign. |
Tip
Telnyx passes TCR and carrier fees through at cost, which makes it the cheapest path for cost-sensitive senders. Twilio has the deepest self-service tooling and a Low-Volume Standard path. Bandwidth is a tier-1 carrier/DCA — good if you want to become your own CSP.
Becoming your own CSP
TCR’s direct customers are CSPs; a brand can’t self-register without one. “Direct TCR access” means becoming your own CSP — a $200 one-time CSP registration (recurring platform costs are separate). Only worth it for high-volume senders or ISVs managing many sub-brands.
Utility tools brands actually need
- Phone / carrier / line-type lookup — scrub landlines & VoIP before sending. Twilio Lookup (Line Type Intelligence ~$0.008/request), Numverify, Abstract API.
- Number reputation / “Spam Likely” checkers — Numeracle Free Caller ID Test, Hiya Caller Reputation, Ring4.
- Privacy policy / SMS terms generators — TermsFeed, Termly, iubenda, GetTerms.io (most have A2P/SMS clauses). Or use our Privacy-clause generator.
- Deliverability monitoring — provider status callbacks + error codes (e.g. Twilio 30007 content filtering, 30023 T-Mobile daily-cap hit), Messaging Insights dashboards.
Watch the delivery stat
The widely cited “~99.2% delivery for registered senders” figure can’t be traced to an authoritative primary source — treat it as vendor marketing. What is confirmed: unregistered traffic is 100% blocked since Feb 2025.
