Robustel R5020Le

Industrial 5G eSIM/eUICC Router with Dual-SIM, 2x LAN, Serial & GNSS


The Robustel R5020Le is an industrial 5G router designed for organisations that want the flexibility of eSIM/eUICC without sacrificing performance or reliability at the edge. Built on the proven R5020-Lite platform, it replaces the second physical SIM slot with an embedded eUICC, combining 1x physical SIM and 1x eSIM to simplify global connectivity, logistics, and lifecycle management.

With its embedded eSIM, the R5020Le lets you remotely download, activate, and switch operator profiles, so you can optimise coverage and commercial terms without visiting site or swapping plastic SIMs. This makes it ideal for large, distributed fleets where truck rolls are expensive and connectivity requirements change over time including cross-border or multi-operator deployments.

The router supports global 5G/4G/3G bands and 3GPP Release 16, runs on RobustOS, and is managed centrally with RCMS for monitoring, configuration, firmware upgrades, and SIM profile changes at scale. Use Ethernet or Wi-Fi as the primary link with automatic failover to 5G/4G, or run 5G as the primary connection; mounting options allow installation in locations that maximise signal strength.

Example R5020Le (R5020-Lite) Use Cases

In-Vehicle Connectivity

Provide secure 5G backhaul for emergency services and fleets with in-vehicle computers, cameras, and location reporting via GNSS; manage updates and diagnostics centrally with RCMS.

SD-WAN 5G Backup

Add a cost-effective 5G backup path to SD-WAN appliances; external mounting improves signal; central monitoring and updates reduce the risk and cost of truck rolls.

High-Speed Industrial IoT

Add high-bandwidth 5G backhaul for robotics, video, telemetry, and data-heavy workflows at plants and yards. Reduce rollout time versus fibre; manage security and updates at scale.
