Do Robustel routers support eSIM?

At present Robustel routers ship with dual SIM slots for removable SIM cards. They do not yet offer native embedded eSIM (eUICC) models, but customers can use removable eUICC SIM cards to enable remote SIM provisioning.

What management software do Robustel routers use?

Robustel routers are powered by RobustOS or RobustOS Pro and can be centrally managed via the Robustel Cloud Manager Service (RCMS), which supports zero-touch provisioning, remote firmware updates, monitoring, and fleet management.

Which industries use Robustel routers?

Robustel routers are used in retail, utilities, transport, logistics, manufacturing, and smart city projects. They provide secure and reliable connectivity for applications such as CCTV, energy monitoring, point-of-sale, remote telemetry, and edge computing.

What are Robustel’s key 4G and 5G models?

Robustel’s key 5G routers include the R5010, R5020, R5020 Lite and R5030. Popular 4G models include the R1520 and R2110. For edge computing, Robustel offers the EG5120, and for LPWAN deployments the R1520LG LoRaWAN gateway.

Robustel: Industrial 4G & 5G Routers, Gateways, and IoT Edge Solutions

Robustel is a global manufacturer of industrial connectivity hardware and software, best known for rugged 4G/5G cellular routers, IoT gateways, and a mature remote management platform. Their devices are widely used in critical infrastructure, retail networks, transport, utilities, manufacturing, and smart city projects worldwide.

Who Robustel Are

Founded with the mission to “make things connected,” Robustel designs and manufactures industrial-grade wireless IoT modems, routers, and gateways across cellular (3G/4G/LTE/5G), Wi-Fi and LPWAN (Cat-M1, NB-IoT, LoRaWAN, BLE). Their offering pairs tough, field-proven hardware with in-house operating systems and a full fleet-management platform, giving enterprises an end-to-end toolset from device to cloud.

Platform Software

RobustOS (Routers)

RobustOS is Robustel’s Linux-based router operating system, developed entirely in-house. It provides the networking stack, multiple VPN options, advanced routing features, an SDK for customisation, and an App Center for modular software add-ons.

RobustOS Pro (Edge Gateways)

For edge computing gateways, RobustOS Pro is based on Debian Linux, with support for Docker, Python, Node.js and C/C++. It enables developers to run containerised apps, AI and analytics workloads directly at the edge, with tight integration into Robustel’s management system.

RCMS (Robustel Cloud Manager Service)

RCMS is Robustel’s IoT device management platform used to deploy, monitor and securely manage routers at scale. Key capabilities include firmware and configuration updates over-the-air, zero-touch provisioning with templates, remote CLI access, live telemetry, rebooting, and real-time dashboards. It helps reduce truck-rolls and speeds up troubleshooting.

Management & Security

Robustel solutions emphasise secure remote management and fleet scalability. RCMS supports zero-touch provisioning, remote CLI access, mass configuration rollouts, and coordinated firmware updates. RobustOS has been penetration-tested for cybersecurity resilience, and Robustel is rolling out compliance with European RED cybersecurity directives across its portfolio.

eSIM / eUICC Status

At present, Robustel routers ship with dual SIM slots for removable SIMs. Native embedded eSIM (eUICC) support is not yet part of the range, but customers can use removable eUICC SIM cards from their provider in Robustel devices. This ensures compatibility with remote SIM provisioning today, with the flexibility to adopt native eSIM SKUs when Robustel makes them available in future.
