SMS-Act Business & Enterprise Solutions
Enterprise teams procuring SMS verification capacity face a different decision than retail users. The 2026 carrier landscape — A2P 10DLC enforcement in the US, TRAI DLT scrubbing in India, Ofcom OBF filters in the UK, Anatel A2P registration in Brazil — has fragmented what used to be a single global number pool into per-country route stacks with sharply different pass rates. This page documents what SMS-Act offers procurement, integration, and platform-engineering teams, what we don't do, and how to evaluate us against Twilio Verify, Vonage Verify, MessageBird Verify, or building in-house against raw carrier interfaces.

Right fit for SMS-Act enterprise
You operate at ≥5,000 verifications/month, your downstream platforms are mainstream (Meta, Google, OpenAI, Microsoft, Discord, dating apps, Uber, Bumble, Stripe, PayPal, Wise, Payoneer, AWS, Azure, Zoho, Slack, GitHub, TikTok, Shopee, Lazada, GCash, Amazon, eBay), and you need country-pool isolation for fraud-control purposes. Procurement is contract-based, not pay-as-you-go.
Wrong fit for SMS-Act enterprise
You need outbound SMS sending — that's A2P, and we are P2A only. Use Twilio, Vonage, MessageBird, Sinch, Plivo, or Azure Communication Services for outbound. You need bank-level KYC bridging (we don't issue regulated bank-of-record numbers). You need single-number permanence (we rotate numbers per activation; if you need sticky numbers for ongoing 2FA on the same end-user, you need eSIM or BYO-SIM, not a virtual SMS receive platform).
Why enterprises route through a verification platform instead of raw carriers
Building OTP receiving in-house against bare carrier APIs is technically possible. It usually fails commercially within 18 months. The root cause is that 2026's regulatory stack makes "carrier" a moving target:
- United States — A2P 10DLC. Since the Campaign Registry rolled out unregistered-traffic throttling (Nov 2023, hardened through 2024-2026), incoming-direction OTPs to unregistered T-Mobile and AT&T sub-pools experience 30-60% silent drop. Workaround requires Campaign Registry brand & campaign registration, which carriers gate.
- India — TRAI DLT. Telecom Regulatory Authority of India's Distributed Ledger Technology platform requires every commercial template to be pre-registered. OTPs whose sender header or content body don't match a registered template are scrubbed. Raw-carrier delivery rate without DLT registration runs <50% on Jio/Airtel/Vi.
- United Kingdom — Ofcom OBF. Ofcom's Originating Body Filter, jointly operated with UK Mobile Network Operators since 2024, prevents non-UK-originated OTPs claiming UK alphanumeric sender IDs. Delivery from non-resident A2P aggregators dropped from ~92% to ~71% during the Q4 2025 enforcement window.
- Brazil — Anatel A2P Registration. Since November 2025, Anatel enforces sender-ID registration for A2P traffic. Unregistered campaigns are throttled across Vivo, TIM, Claro, and Oi.
- Indonesia — Kominfo carrier whitelisting. Telkomsel, Indosat, and XL Axiata require pre-registration of A2P templates as of 2024. Bypass via international gateways has tightened.
The aggregate effect: a 2021-style "buy ten Twilio numbers and call it a day" architecture has dropped from ~88% global pass rate to roughly 62% in Q1 2026. Verification-platform middleware (Twilio Verify, Vonage Verify, SMS-Act, etc.) absorbs this complexity by maintaining country-specific route stacks, pre-registered templates where the regulator demands them, and HLR-aware number filtering.

The 5-tier enterprise procurement framework
Different verification volumes need different procurement shapes. Match yourself to a tier before quoting.
| Tier | Monthly verifications | Pricing model | Account shape | Typical industry |
|---|---|---|---|---|
| Self-serve | < 500 | Pay-as-you-go | Single user | Indie devs, small SaaS |
| Team | 500 – 5,000 | Pre-paid balance + discount tier | One billing account, 3-5 users | Growth-stage SaaS, agencies |
| Business | 5,000 – 50,000 | Monthly commitment + overage | One billing account, shared dashboard | Mid-market SaaS, marketplaces |
| Enterprise | 50,000 – 500,000 | Quarterly commitment | Dedicated commercial contact | Fintech, ad networks, dating platforms |
| White-label | 500,000+ | Per-verification reseller margin | Commercial arrangement, case by case | Resellers, MVNOs, identity vendors |
The Business and Enterprise tiers are the procurement-friendly ones. They include written commercial terms, monthly invoicing, a dedicated commercial contact, and country-pool isolation (your verifications draw from a sub-pool kept separate from the general retail pool, which reduces fraud-trigger contamination from other users).
Failure decode table: what to do when OTPs stop arriving
| Symptom | Likely root cause | Resolution path |
|---|---|---|
| "Number already in use" on the downstream platform | Number was previously used on that platform | Draw a fresh number — pools deduplicate per platform, but residual collisions exist on the long tail |
| OTP arrives but downstream rejects code | Code expired (most platforms time out at 5-10 min) | Copy the code into the target platform promptly; the dashboard surfaces it as soon as it lands |
| OTP never arrives, credits refunded | Carrier route dropped the message at the regulatory filter | Release the number and draw again on a different country |
| OTP never arrives, balance NOT refunded | OTP was likely delivered but to a recycled number whose previous holder caught it | Rare in our pool; report to support — manual refund within 48h |
| Sudden 30%+ drop across one country | Regulatory enforcement event (e.g., Anatel Nov 2025) | Route the country to a different sub-pool; CSM proactively notifies Enterprise tier |
How working at volume actually looks today
SMS-Act has no public API. There are no endpoints, no API keys, no webhooks, and no SDKs — every verification is drawn and read in the web dashboard. This is the single most important thing for a procurement or platform team to know before evaluating us, because it rules out entire architectures.
What that means in practice:
- No CI/CD or QA-pipeline integration. If your requirement is automated test accounts provisioned by a build job, SMS-Act cannot serve it today. A sending-side provider with a programmatic verification product is the right category for that.
- Volume is operational, not programmatic. Teams running thousands of verifications a month do so with people working the dashboard, not with a job queue. Staff that accordingly.
- What scales well anyway: country selection and route quality, per-attempt refunds with no threshold, and pool isolation on contracted tiers. Those are pool-side properties and do not depend on an integration surface.
If a public API becomes available, it will be documented on this page. Until then, treat any third-party listing that advertises an SMS-Act API as inaccurate.
What the 5-tier framework explicitly excludes
We do not offer:
- A public API, webhooks, or SDKs of any kind — the platform is dashboard-only
- Outbound A2P marketing/transactional SMS — use Twilio, Vonage, MessageBird, Sinch, Azure Communication Services
- Voice OTP (TTS or pre-recorded) — use Twilio Voice, Vonage Voice, Plivo
- Programmable voice calls in general
- Bank-of-record sticky numbers for 2FA over months/years — use eSIM provisioning (eSIM.net, Truphone) or BYO-SIM with virtual operator
- WhatsApp Business API messaging — that's BSP territory (Twilio, 360dialog, Meta Cloud API)
- Identity-graph services (resolving "is this person real") — use Persona, Onfido, Veriff, Trulioo
- Banking-grade KYC — use Sumsub, Jumio, ComplyAdvantage
Pretending we do these would invite procurement misalignment and compliance risk for you. The honest framing is: SMS-Act is a P2A receiving infrastructure for OTPs originated by third-party platforms.
What can be committed in writing (Enterprise tier)
Terms are contractual and signed per customer. Because there is no API, commitments are about pool quality and money — not endpoint availability:
- Tier-1 country pass rate: ≥85% (US, UK, DE, FR, IN, ID, PH, BR, RU, JP) monthly aggregate
- Tier-2 country pass rate: ≥75% (remaining 90+ countries)
- Median OTP latency: under 30 seconds from drawing the number to the code appearing in the dashboard
- Refund triggers: any unfilled activation returns credits automatically, with no minimum-balance threshold
- Incident response: P0 (dashboard unavailable) acknowledged in 30 min; P1 (country-wide degradation) in 2h
- Service credits: negotiated against the agreed pass-rate threshold
Frequently asked enterprise questions
Q: Are SMS-Act and Hero-SMS the same company? A: No. SMS-Act has operated independently since 2023 with separate infrastructure, ownership, and roadmap. SMS-Activate's 2025-12-29 shutdown notice directed users to hero-sms.com in December 2025. SMS-Act predates that transition. Procurement teams should treat these as three distinct vendors when comparing options.
Q: How does SMS-Act compare on price to Twilio Verify? A: Per-verification, SMS-Act is typically 40-70% lower on Tier-1 countries because we operate on a different cost basis (we do not run an A2P sending stack). Twilio Verify's premium covers their A2P infrastructure and Verify-specific fraud product. If you are sending and receiving, Twilio's bundled pricing may be competitive. If you are receiving only, we are almost always cheaper.
Q: What's the typical fraud-protection stack on Enterprise tier? A: Pool-side: HLR pre-filter (kicks out fixed-line / non-mobile numbers before they reach a registration flow), number-recycling cooldown, per-platform deduplication, anomaly detection on burst-buying patterns.
Q: How long is the contract minimum? A: Quarterly commitment (3 months) for Enterprise tier, monthly for Business. White-label requires 12-month commitment with quarterly volume reviews.
Q: Can SMS-Act sign a DPA (Data Processing Agreement) under GDPR? A: Yes. Our standard DPA covers Article 28 processor obligations, sub-processor disclosure, EU SCCs for international transfer, and 72-hour breach notification. Available under NDA from biz@sms-act.net.
