SMPP Connectivity
Direct carrier-grade SMPP gateway for enterprise and operator-class SMS. High-throughput binds, dedicated routes, and multi-bind resilience built for platforms that cannot afford downtime.
High-Throughput Binds
When your platform needs to move millions of messages without queuing delays or throughput throttling, SMPP high-throughput binds give you direct, protocol-level control over your messaging pipeline. Our SMPP gateway supports configurable submit_sm TPS limits per bind, with burst capacity available above your base allocation for traffic spikes.
Unlike HTTP API integrations where throughput is abstracted away, SMPP gives your platform engineers direct visibility and control. Window size negotiation at bind time lets you fine-tune the balance between throughput and latency for your specific traffic profile. We support both SMPP v3.3 and v3.4, and our technical onboarding team will work with you to determine the optimal configuration for your use case before go-live.

Dedicated Routes
Shared routing pools are a source of unpredictability — delivery quality fluctuates as other customers' traffic competes for the same capacity. Dedicated routes eliminate this variability entirely. We provision private routing paths exclusively for your SMPP traffic, with capacity, quality, and latency commitments that cannot be affected by other accounts.
Dedicated routes are the standard requirement for financial services platforms, telecom operators, and any customer whose business depends on predictable, consistent SMS delivery. We maintain direct operator connections to major markets, and where direct connections exist, your dedicated route uses them. Country and network-level route selection gives your operations team granular control over exactly which paths are used for each destination market, with route performance reporting available in real time.

Multi-Bind Support
Production SMPP deployments should never depend on a single session. Multi-bind support allows your platform to maintain multiple concurrent SMPP sessions against our gateway simultaneously, distributing outbound throughput across connections and providing automatic failover if any individual session drops or becomes degraded.
Each bind can be independently configured for throughput, bind mode, and delivery receipt routing — giving you full architectural flexibility. Load balancing across binds is handled at the application layer, so your platform can implement any distribution strategy. Session health is monitored continuously, and our gateway initiates enquire_link cycles to detect stale sessions before they cause message loss. Zero-downtime maintenance windows are achievable through bind rotation.

- Multiple concurrent active SMPP sessions
- Independent TPS allocation per bind session
- Automatic session failover on disconnection
- Load distribution across active binds

The Protocol of Choice for High-Volume Platforms
SMPP is the standard for any platform that cannot accept the throughput limitations or latency overhead of HTTP-based messaging.
From Setup to Live in Days
Our technical team handles provisioning and supports your integration from first bind to full production traffic.
Credentials provisioned
We configure your SMPP account with agreed TPS limits, bind mode, and routing parameters. IP whitelisting and dedicated port allocation are set up before your first connection.
Connect and configure
Your SMPP client connects to our gateway endpoint. Our technical team supports your bind configuration, window size tuning, and test message verification during onboarding.
Monitor and scale
Live throughput metrics, delivery rate data, and session health monitoring give your team full operational visibility. Scale TPS or add binds as your volume grows.
SMPP Connectivity — Frequently Asked Questions
What is SMPP connectivity and why use it instead of HTTP API?
SMPP (Short Message Peer-to-Peer) is a protocol designed specifically for high-volume SMS exchange between platforms and carrier networks. Unlike HTTP APIs, SMPP maintains a persistent TCP connection, supports much higher throughput, provides lower latency, and gives platforms direct protocol-level control over session behaviour, window sizes, and delivery receipt handling. SMPP is the standard choice for platforms processing thousands of messages per second.
What SMPP protocol versions do you support?
We support both SMPP v3.3 and SMPP v3.4. The majority of enterprise deployments use v3.4, which includes enhanced error handling and additional PDU types. We recommend v3.4 for new integrations but fully support v3.3 for platforms with existing implementations. Our technical team will advise on any version-specific configuration requirements during onboarding.
How many concurrent SMPP binds can I have?
There is no hard limit on concurrent binds — the number is agreed as part of your service configuration based on your throughput requirements and architecture. Most customers operate between 2 and 10 concurrent binds, with financial services and aggregator customers often running more for redundancy. Contact our team to discuss the right bind count for your expected volumes.
What TPS rates are available?
TPS (Transactions Per Second, i.e. submit_sm operations) is configurable per bind. We support from low-volume configurations of 10 TPS up to 1000+ TPS per bind for high-throughput deployments. Aggregate TPS across multiple binds can scale to very high volumes for aggregator and operator-class customers. Your base TPS is agreed in your service contract, with burst capacity available above that threshold.
Do you support inbound (MO) messages via SMPP?
Yes. Inbound MO (Mobile Originated) messages are supported via receiver or transceiver binds. MO routing can be configured per bind, with delivery to your SMPP receiver or forwarded to a webhook endpoint. We support long code and short code inbound routing depending on your market requirements.
How long does SMPP onboarding take?
For standard configurations, SMPP credentials can be provisioned within 1–2 business days of agreement. Our technical team will schedule an onboarding call to walk through bind configuration, test message verification, and throughput validation. More complex deployments involving dedicated routes, custom TPS profiles, or specific compliance requirements may take slightly longer. We aim to get every customer live as quickly as possible.
