One gateway for a
nation's messages.
OTPs, transactional notifications, and marketing campaigns — delivered reliably across every operator on one governed, multi-tenant platform.
Ghasi SMS Gateway is the full A2P stack: SMPP connectors bind directly to mobile operators, an orchestrator routes and retries every message, a DLR processor tracks delivery end to end, and consent, campaigns, billing, and real-time analytics are built in — not bolted on. Spec-first, so services, topics, routes, and contracts are generated from validated specs.
A2P messaging in emerging markets is a patchwork — and it leaks.
Businesses that need to reach customers by SMS end up wiring themselves to each operator by hand. Every connection is bespoke, every contract is separate, and nobody can see what actually got delivered.
The result is a fragile, invisible mess that no single team fully controls:
- Direct-to-operator integrations — a separate SMPP bind, contract, and price list negotiated per network, maintained by hand.
- No delivery visibility — messages are fired and forgotten, with delivery receipts unparsed or thrown away.
- No consent management — opt-ins, opt-outs, and DND lists live in spreadsheets, if they exist at all.
- Spam and DND violations — no enforcement layer between the sender and the subscriber, and regulators are watching.
- No unified analytics — throughput, latency, and cost sit in each operator's portal, never in one place.
- OTP failures that lose customers — a delayed or dropped one-time password is an abandoned signup or a failed payment.
Left unsolved, the cost compounds:
- Failed OTPs quietly become failed onboardings, failed logins, and failed checkouts.
- Marketing spend disappears into messages that were never delivered and never measured.
- A single DND or consent violation can trigger fines, throttling, or an operator cutting the sender off.
- Every new operator or country means another integration project from scratch.
The country doesn't need ten fragile integrations. It needs one gateway that speaks to every operator, guarantees delivery, enforces consent, and shows exactly what happened to every message.
One API to every operator. One place for every message.
Ghasi SMS Gateway sits between your applications and the mobile networks. You submit a message once; the platform validates it, routes it to the right operator, delivers it, confirms it, and bills it — the same way, every time.
The vision: a single, sovereign, multi-tenant A2P backbone that any business, aggregator, or operator can build on — spec-first, so every service, Kafka topic, Kong route, and Keycloak role is generated from machine-validated contracts rather than tribal knowledge.
Where it runs
Built for markets where reliable, governed messaging infrastructure doesn't yet exist as a shared utility.
Afghanistan — reference jurisdiction
The platform is designed first for the Afghan market: local operators, local numbering, and local regulatory realities are the reference model that everything else generalizes from.
Asia & MENA
The same multi-operator, multi-tenant architecture ports to neighboring markets where senders face the same fragmented, per-operator status quo.
Africa & beyond
Operator connectors, consent rules, and billing plans are configuration — not forks — so a new country is an onboarding exercise, not a rewrite.
The path of a single message
Every message — an OTP, a shipping alert, a campaign blast — travels the same governed path from your application to the subscriber's handset and back.
Messages don't get dropped. They get delivered — or accounted for.
A national gateway is judged on one thing: did the message arrive? Ghasi SMS Gateway is built so that a message accepted is a message that either reaches the handset or is fully explained by a delivery receipt.
A nationwide OTP surge — every bank, wallet, and app authenticating at once during a public deadline — hits the gateway. Store-and-forward queues absorb the spike, least-cost routing spreads load across operators, failed binds fail over automatically, and not a single one-time password is dropped.
What makes delivery reliable
Store-and-forward queue
Accepted messages are durably persisted before they leave the gateway. A broker outage or operator hiccup delays delivery — it never loses the message.
Operator failover
Multiple SMPP binds per operator and multiple routes per destination mean a dead session or throttled operator reroutes automatically, without dropping traffic.
Retry & DLR
Undelivered messages retry on a backoff schedule, and every delivery receipt is parsed and mapped back to the original message so status is always truthful.
Idempotent submission
A client message ID de-duplicates retried submissions, so a flaky network on the sender's side never turns one OTP into three.
What that buys you
Predictable throughput
Per-tenant and per-operator rate limits smooth bursts and protect binds, so one noisy sender can't starve the rest of the country.
Honest delivery status
Every message carries a real, DLR-backed state — accepted, en route, delivered, failed, or expired — never a hopeful guess.
No silent loss
A message that cannot be delivered lands in a dead-letter channel with a structured reason, not a shrug. Nothing disappears quietly.
Graceful degradation
When an operator degrades, the gateway sheds load, reroutes, and keeps the healthy paths flowing instead of collapsing.
Routing, fraud, and content that get smarter every message.
The gateway sees every message, every route, and every delivery receipt in the country. That stream is exactly what intelligent routing, fraud detection, and content assistance need to make each message cheaper, safer, and more likely to land.
Intelligence is advisory and auditable. Every automated routing or fraud decision is logged with its inputs, and consent and compliance rules are hard constraints the models operate inside — never around.
Smart routing
Least-cost and best-delivery routing picks the operator path that balances price against real, observed delivery rates for each destination — and adapts as networks change.
Fraud & spam detection
Traffic-pattern analysis flags SIM-farm behavior, artificially inflated traffic, and spam bursts before they burn budget or trigger operator penalties.
Delivery-time prediction
Per-operator, per-hour models estimate when a message will actually land, so senders can time OTPs and campaigns for the moment recipients are reachable.
Campaign content assistance
Drafting help for campaign copy — length, encoding, and segmentation aware — so a message fits in the fewest SMS parts without mangling the meaning.
Opt-out intent detection
Inbound replies are read for stop/unsubscribe and complaint intent in local languages, so consent state updates instantly — not after the next fine.
Per-tenant budgets
Spend forecasting and anomaly alerts per tenant catch a runaway loop or a compromised key before it becomes a five-figure bill.
Intelligence operates inside the rules, not above them.
- Every routing and fraud decision is recorded with the signals that produced it, so any outcome can be explained and audited.
- Consent, DND, and quiet-hours rules are enforced as hard constraints — no model output can override an opt-out.
- Tenants stay isolated: one tenant's traffic never trains against or leaks into another tenant's models or data.
- Automated actions are reversible and rate-limited, and a human can always take the wheel.
From submission to reconciliation — one governed pipeline.
Every message flows through the same stages: submitted through the API, validated, routed, delivered by an operator, confirmed by a delivery receipt, counted into analytics, and reconciled into billing. Each stage is an owned, spec-defined service.
The core you get on day one
API submission
A clean OpenAPI 3.1 REST surface behind the Kong gateway — send a single message or a batch, with idempotency keys and per-key rate limits.
Campaign management
Create, schedule, and throttle bulk campaigns against contact lists, with per-campaign sender IDs, templates, and consent checks.
Template & sender-ID management
Register and approve sender IDs and message templates once, then reuse them across senders with the compliance state attached.
Consent registry
A single source of truth for opt-in, opt-out, and DND status per subscriber — checked on every send, updated on every reply.
Delivery tracking
Live per-message status backed by parsed delivery receipts, queryable by API and visible in the portal.
Billing & usage
Every accepted and delivered message is metered, rated against the tenant's plan and operator cost, and rolled into invoices.
The services behind it
The pipeline is composed of independent, spec-first services — each owning its data, its topics, and its contracts.
SMPP operator connectors
Native SMPP 3.4 / 5.0 binds to each mobile operator, handling transmitter/receiver sessions, enquire-link heartbeats, PDU parsing, and TPS throttling.
Webhook dispatcher
HMAC-signed delivery and inbound webhooks pushed to tenant endpoints, with exponential-backoff retries and a dead-letter queue.
Two-way & inbound messaging
Inbound MO messages and replies are received, correlated to conversations, and surfaced for consent updates and customer workflows.
Number & short-code management
Provision and govern long numbers, short codes, and sender IDs, mapped to tenants, operators, and approval state.
Alerting
Operational alerts on bind health, queue depth, delivery-rate drops, and budget anomalies — routed to the teams that own them.
Analytics dashboards
ClickHouse-backed dashboards for throughput, delivery, latency, and cost, sliced by tenant, operator, campaign, and destination.
Senders, developers, operators, and compliance officers all act on the same pipeline — each seeing only their tenant, each governed by the same contracts.
Built for a country's worth of traffic — and to prove it.
Reaching a nation means sustaining high throughput across every operator while watching delivery in real time. The gateway is engineered for both: scale on the send path, and truth on the analytics path.
Real-time delivery analytics
Powered by ClickHouse, so millions of events per day turn into answers in seconds — not overnight batch reports.
Live delivery rates
Delivery success, failure, and expiry rates stream in per operator, per destination, and per campaign as receipts arrive — no waiting for a nightly job.
Latency & throughput
Submission-to-delivery latency and messages-per-second are tracked continuously, so a slowing operator is visible the moment it starts to drift.
Cost & margin
Every message carries its operator cost and its rated price, so spend, revenue, and margin are queryable by tenant and campaign in real time.
Operator & network monitoring
The gateway watches every operator link the way an NOC watches a network — because at national scale, an unhealthy bind is a national incident.
- Per-operator bind health, session state, and enquire-link heartbeats, with automatic re-bind and failover.
- Delivery-rate and latency baselines per operator, with anomaly detection when a network degrades.
- Queue depth and retry backlog per route, so congestion is caught before it becomes dropped traffic.
- Throughput headroom against per-operator TPS limits, so senders and operators know how much capacity is left.
What national scale looks like
One platform, three ways to run it.
The same multi-tenant core serves a single business sending its own OTPs, an aggregator reselling capacity to hundreds of customers, and a national operator-grade platform — the difference is configuration, not a different product.
Deployment profiles
Single business
One company sending its own transactional and marketing SMS through the customer portal and API — sender IDs, templates, and billing scoped to a single tenant.
Aggregator / reseller
A messaging aggregator running many sub-accounts under one platform, with per-customer isolation, pricing, quotas, and white-labeled access.
National platform
An operator-grade deployment with high availability, direct operator interconnects, and the scale and monitoring to run as shared national infrastructure.
What every deployment inherits
Multi-tenancy to the core
Tenant identity is carried through auth, application code, database rows, cache, message headers, and logs — isolation is the default, not an add-on.
Modular licensing
Turn services on as you need them — campaigns, two-way messaging, analytics, billing — without redeploying the platform.
Sovereign hosting
Runs on infrastructure you control, in-country, so message content and subscriber data never have to leave the jurisdiction.
Kong-fronted API
Every tenant reaches the platform through one governed edge — authenticated, rate-limited, and observable at the gateway.
Keycloak identity
Roles, groups, and API-key clients are managed in a single realm, so who-can-do-what is centralized and auditable.
GitOps operations
Kubernetes, Helm, and ArgoCD mean deployments are declarative and reversible, and the running platform matches the spec.
Interoperable by protocol. Compliant by design.
A national gateway has to speak the operators' protocols and answer to the regulators' rules. Ghasi SMS Gateway is built on open, published standards at every boundary.
SMPP 3.4 / 5.0
Native Short Message Peer-to-Peer binds to mobile operators, with transmitter/receiver sessions, DLR handling, and TPS throttling per the protocol.
GSMA & SMForum A2P
Sender-ID, aggregator, and A2P traffic practices align with GSMA and SMForum guidance so traffic is recognized and trusted by operators.
Consent, DND & regulation
Opt-in / opt-out and Do-Not-Disturb enforcement, quiet-hours handling, and TCPA-style unsubscribe honoring are enforced on every send.
Security & privacy
PCI-DSS-adjacent handling for OTP and payment traffic, OWASP ASVS practices, and encryption in transit and at rest across the platform.
APIs & events
OpenAPI 3.1 REST, AsyncAPI 3.0 events, JSON Schema 2020-12 payloads, and CloudEvents 1.0 — with signed webhooks and a schema registry as the contract authority.
Governance & residency
ISO 27001-aligned controls, full audit trails, and in-country data residency so subscriber data and message content stay within the jurisdiction.
Spec-first means these aren't aspirations in a slide — services, topics, routes, and roles are generated from the specs and gated in CI.
One gateway, every role in the messaging chain.
From the business firing an OTP to the operator carrying it, everyone in the A2P chain works against the same platform — each with a role scoped to what they need.
From fragmented and blind to unified and accountable.
Set the per-operator status quo against a single governed gateway and the difference is stark — row by row, this is what changes.
What one gateway makes possible.
Give a market a single reliable messaging backbone and the second-order effects compound — for the country and for the businesses built on top of it.
A national messaging backbone
- Every bank, wallet, government service, and app authenticates and notifies through one reliable, in-country gateway.
- Regulators get enforceable consent and a real audit trail instead of an ungoverned free-for-all.
- Operators receive clean, throttled, consented A2P traffic from a single trusted partner.
- The country keeps message content and subscriber data on sovereign infrastructure.
- New services launch on messaging that already works — instead of rebuilding it each time.
A business built on the platform
- An aggregator onboards hundreds of customers on shared infrastructure with per-tenant isolation and pricing.
- Least-cost routing and real-time margin analytics turn messaging into a managed, profitable book.
- Modular services — campaigns, two-way, analytics — become upsells, switched on without redeployment.
- White-labeled portals and APIs let resellers put their own brand on a proven platform.
- Growth into new operators and new countries is configuration, so the business scales without re-platforming.
Let's put your country's messages on one gateway.
Whether you're a business tired of per-operator integrations, an aggregator ready to scale, or an operator building national infrastructure — we'd like to understand what you're sending and where.
