Why on-premise?

Why choose a hardware SMS gateway?

Six reasons that concern service continuity, data ownership, and operational control.

01

It also works without Internet

SIM communications do not depend on your primary Internet connection.

SIM communications do not depend on your primary Internet connection.

02

Data ownership

SMS, logs and metadata remain in your infrastructure.

Message history and system events reside on the gateway, where the access and retention policies already adopted apply.

03

Reducing dependence on providers

Maintain control over communication paths.

Changes in service, price list, or routing from an external provider do not in themselves determine the continuity of notifications.

04

Cost control

Use existing SIMs and mobile contracts when appropriate.

The choice of operator and plan remains an internal decision, assessed on the basis of the organization's actual volumes.

05

Critical communications

Designed for infrastructures where message delivery is essential.

Multi-SIM configurations, routing rules and failover reduce single points of failure on the notification channel.

03

A shared gateway

IT, DevOps, and operations can use the same infrastructure with different roles.

Separate users and permissions allow you to distinguish which team and system sent each message.

Web Console

Your entire SMS infrastructure in a single console.

A web interface to manage messages, SIMs, modems, integrations and permissions, without accessing the gateway command line.

Real-time status

Queues, deliveries, modems and SIMs in a single operational view.

Routing rules

Priority, SIM selection, and failover behavior.

Users and roles

Separate permissions for IT, DevOps, and Operations teams.

Logs and events

History can be consulted for diagnostics and internal checks.
