White-label SMPP gateways for OTP, bulk alerts, shortcodes, and two-way messaging — built for telcos, banks, and aggregators across Africa, the Middle East, and Asia.
In2Excel builds white-label enterprise SMS platforms that you run under your own brand — routing, sender IDs, client accounts, and billing included. This is platform software for telcos, banks, fintechs, and aggregators, not a shared bulk-SMS credit account.
We integrate operator and aggregator routes, wire up shortcodes (MO/MT), and tailor every workflow — from OTP and transactional alerts to two-way interactive services.
Beyond bulk messaging, we engineer alerting, scheduling, OTP/PIN, subscription billing, and two-way SMS with airtime charging via Service Delivery Platforms. Protocol expertise includes SMPP, SIP, SOAP, and REST, with full Unicode support for multi-language messaging worldwide.
Deployments run on Linux with optional Kubernetes for high availability and horizontal scale — proven at 45 million+ SMS per month.
SMPP (Short Message Peer-to-Peer) is the backbone of our platform, enabling high-speed, reliable message exchange with operators, aggregators, and enterprise systems. We also support SIP for voice-SMS convergence and SOAP/REST for web service integrations.
Production integrations with mobile network operators and partners worldwide, including:
Transactional, promotional, and interactive messaging for every industry
Secure one-time passwords for login, registration, and transaction authentication with prioritised delivery.
Reminders, service alerts, appointment confirmations, and broadcast notifications at scale.
Transaction alerts, mini-statements, balance inquiries, and fraud notifications for financial services.
Interactive campaigns, audience feedback, and market research via two-way shortcode SMS.
Real-time status updates for deliveries, field operations, and supply-chain events.
Points accrual, reward redemption, opt-in marketing, and subscription content with airtime billing.
Built-in capabilities for production messaging infrastructure
Scale to tens of millions of messages per month with controlled TPS, connection pooling, and resilient retries.
End-to-end delivery status, per-route routing, real-time dashboards, and full audit trails.
Full Unicode support and automatic concatenation for multi-language and extended-length messages.
REST/SOAP APIs, SMPP, and SIP; shortcode MO/MT integrations with operators and aggregators.
IP allowlists, key rotation, rate limiting, RBAC, and audit logging for messaging infrastructure.
Operational KPIs, delivery trends, campaign performance, and exportable reports.
Why enterprises choose a custom SMS platform over off-the-shelf gateways.
Kubernetes-backed horizontal scaling handles traffic spikes with zero downtime.
Connects to your CRM, ERP, billing, or core banking system via REST, SOAP, or SMPP.
Built-in airtime charging and Service Delivery Platform (SDP) integration for monetized SMS services.
Pre-built operator connectors and proven architecture cut integration time significantly.
Many teams only need to send messages through someone else's API. This platform is for organisations that need to own the messaging layer — route selection, sender ID policy, shortcode sessions, client portals, and reconciliation.
Pair messaging with a USSD platform, mobile VAS / SDP, missed call workflows, or a utility and recharge service on the same operator relationships.
Discovery & Requirements: We map messaging workflows, operator landscape, and throughput needs to define the right architecture.
Platform Design: Protocol selection (SMPP/REST/SOAP), routing logic, security model, and integration points are documented and approved.
Build, Test & Integrate: Core platform development, operator connectors, load testing, and end-to-end UAT with DLR verification.
Go-Live & Support: Production deployment, monitoring, handover documentation, and ongoing SLA-backed operational support.
An enterprise SMS platform is a messaging system that connects to mobile operators or aggregators via SMPP or APIs to send and receive SMS at scale — including OTP, alerts, bulk campaigns, and two-way shortcode services with delivery reports and audit trails.
Yes. SMPP is the core protocol for high-throughput SMS exchange. We implement connection pooling, controlled TPS, delivery reports (DLR), retry logic, Unicode and concatenated messages, and routing to operators and aggregators.
Yes. We build OTP and PIN flows for login, registration, and transaction authentication, plus transactional alerts for banking, logistics, appointments, and service notifications with prioritised delivery paths.
Yes. MO/MT shortcode integrations support interactive services such as voting, subscriptions, keyword campaigns, and customer replies — with session logic and optional airtime or premium billing.
Deployments run on Linux with optional Kubernetes for high availability and horizontal scale. Production systems have handled 45 million+ SMS per month with 99.9% uptime targets.
Yes. We connect via REST, SOAP, or SMPP to CRM, ERP, billing, and core banking systems so messages are triggered by business events and delivery status is written back to your systems.
Yes. The platform is deployed under your brand, domain, and short codes. You own routing rules, sender IDs, client accounts, billing, and delivery reports — instead of reselling credits from a shared gateway.
We deploy enterprise SMS platforms across Africa, the Middle East, and Asia, with operator connections including MTN, Airtel, Safaricom, Vodacom, Glo, e&, du, stc, Ooredoo, Zain, and other regional networks.
