Robustel R5020Le

Industrial 5G Dual-SIM Router with 1x eSIM/eUICC, 1x 2FF SIM, 2x ETH, Serial & GNSS


The Robustel R5020Le is an industrial 5G router that brings eSIM/eUICC flexibility to high-performance edge deployments. Built on the R5020-Lite platform, it uses a hybrid SIM designโ€”one physical SIM plus an embedded MFF2 eSIM compliant with GSMA SGP.22โ€”so organisations can standardise global rollouts while reducing SIM logistics and long-term operational overhead.

The embedded eSIM enables over-the-air profile download, activation, and switching, making it easier to adapt operator choices as coverage, roaming needs, or pricing change across regions. It also adds practical safeguards for scaled deployments, including secure profile control, automatic rollback to a working profile if provisioning fails, and profile rotation to avoid locking fleets into long-term roaming arrangements or maintenance-heavy SIM swaps.

On the connectivity and management side, the R5020Le supports global 5G/4G/3G bands and 3GPP Release 16, runs RobustOS, and can be managed centrally through Robustel Cloud Manager Service (RCMS) for monitoring, configuration, firmware upgrades, and eSIM profile operations. With flexible WAN designโ€”Ethernet or Wi-Fi as primary with cellular failover, or 5G as the main linkโ€”and multiple mounting options to improve signal placement, itโ€™s well suited to distributed sites where performance and uptime matter as much as provisioning efficiency.
