Robustel R5020e
eSIM Router
Industrial Dual-SIM 5G Router with 1x eSIM/eUICC, 1x 2FF SIM, 4x LAN, Serial, GNSS & PoE
The Robustel R5020e is an industrial 5G router designed for high-speed cellular connectivity in distributed IoT, enterprise, and industrial networking applications where remote SIM lifecycle management is a major operational requirement.
Built on the proven R5020 platform, the R5020e combines global 5G/4G/3G cellular support with a hybrid 1 × Mini SIM + 1 × MFF2 eSIM architecture. This gives organisations a practical way to deploy cellular routers across regions, manage connectivity profiles remotely, and reduce the need for physical SIM handling during rollout, service changes, or long-term fleet maintenance.
For network integration, the R5020e provides 4 × Gigabit Ethernet ports, configurable as 4 × LAN or 1 × WAN + 3 × LAN, plus Wi-Fi 5, RS-232, RS-485, 1 × DI, 1 × DO, optional GNSS, and 802.3at PoE-PD support on ETH0. Built on RobustOS, it supports common industrial networking functions including VPN tunnels, routing, firewall features, Modbus RTU to TCP, Smart Roaming V3, and RCMS-based remote management.
The result is a high-speed industrial 5G router for organisations that need more than cellular performance alone: they need reliable connectivity, flexible carrier profile management, and a scalable way to operate routers across regions, sites, and lifecycle stages.

Example R5020 Use Cases
In-Vehicle 5G Hub

Provide secure 5G backhaul for onboard systems, passenger Wi-Fi, telemetry, and vehicle-based equipment, with SIM + eSIM connectivity to simplify carrier profile management across fleets, regions, and service contracts. Remote eSIM provisioning helps reduce physical SIM handling when vehicles are deployed, reassigned, or moved between network environments.
Primary & Backup Broadband

Use the R5020e as primary wireless broadband or automatic failover for branch offices, retail sites, smart buildings, and distributed enterprise networks. eSIM/eUICC support makes it easier to activate, change, or retire cellular profiles remotely, reducing the need to ship region-specific SIM cards or send technicians to site.
High-Speed Industrial IoT

Add high-speed 5G backhaul for robotics, CCTV, telemetry, automation systems, and industrial equipment. The R5020e’s SIM + eSIM architecture helps organisations manage connectivity profiles remotely across distributed industrial sites, reducing SIM-swap maintenance and supporting long-term fleet lifecycle control.
