Robustel R2011e
Industrial 4G/LTE Dual-SIM Router with 1x eSIM/eUICC, 1x 2FF SIM & 5x ETH
The Robustel R2011e is an industrial 4G/LTE router that pairs the stability of the R2011 platform with a mixed SIM design: one physical SIM plus an embedded MFF2 eSIM/eUICC aligned to the GSMA SGP.22 standard. You retain dual-path resilience, but replace the second removable SIM with a digitally managed profile—better suited to long-running deployments and fleets that move across borders or evolve over time.
Its eSIM capabilities let you provision and switch operator profiles remotely, adjusting coverage, roaming behaviour, and commercial terms without on-site intervention. Built-in safeguards make this practical at scale, including secure profile control, automatic fallback to a known-good profile if activation fails, and profile rotation to reduce reliance on fixed roaming arrangements and avoid maintenance-heavy SIM changes.
For networking, five 10/100 Ethernet ports (configurable as 4×LAN + 1×WAN or 5×LAN) support straightforward segmentation on-site without an external switch. Link Manager maintains continuity by orchestrating failover across cellular, Ethernet, and optional Wi-Fi, while remote administration scales through Robustel Cloud Manager Service (RCMS) for monitoring, configuration, and Zero-Touch eSIM provisioning across large device estates.

Example R2011e Use Cases
Branch Network Aggregation
Provide reliable cellular connectivity for branch networks with multiple wired devices. Multi-Ethernet ports enable simple aggregation, with SIM + eSIM redundancy and centralized management via RCMS.
Industrial Control Cabinets
Connect PLCs, HMIs, and edge devices inside control cabinets using multiple Ethernet ports. eSIM simplifies operator management while failsafe mechanisms ensure stable connectivity.
Infrastructure & Facility Support
Deliver secure IP backhaul for facilities requiring several wired endpoints. Remote provisioning and monitoring via RCMS reduce on-site maintenance effort.
