Robustel R1520e Global
eSIM Router
Globally certified industrial Dual-SIM 4G/LTE router with 1x eSIM/eUICC, 1x 2FF SIM, 5× LAN, GNSS, serial, DI/DO, and analog input.
The Robustel R1520e Global is an industrial 4G/LTE VPN router designed for OEMs, system integrators, fleet operators, and distributed enterprises that need reliable cellular connectivity across multiple countries, carriers, and deployment environments.
Built on the proven R1520 Global platform, the R1520e combines wide 4G/LTE, 3G, and 2G band support with a hybrid 1 × eSIM MFF2 + 1 × physical SIM architecture. This gives organisations the flexibility of a removable SIM while adding the operational advantages of embedded eSIM/eUICC for remote profile provisioning, carrier changes, and long-term device lifecycle management.
The R1520e supports GSMA SGP.22 eSIM profile download and removal operations, with typical support for up to 6 eSIM profiles. When used with Robustel Cloud Manager Service (RCMS) enterprises can remotely assign and activate eSIM profiles across router fleets, helping reduce manual SIM handling, simplify international rollout, and avoid unnecessary site visits when connectivity requirements change.
For industrial integration, the R1520e Global provides 5 × 10/100 Mbps Ethernet ports, configurable as 5 × LAN or 1 × WAN + 4 × LAN, plus RS-232, RS-485, 1 × DI, 1 × DO, 1 × analog input, Wi-Fi, GNSS, USB, optional PoE-PD on ETH0, and RobustOS networking features including VPN, routing, firewall, Smart Roaming, and RCMS remote management.

Example R1520e Global Use Cases
Heavy Equipment Fleets
Deploy LTE connectivity for heavy equipment fleets operating across sites, regions, or countries. The R1520e Global supports secure backhaul for telematics, diagnostics, and operator systems, while SIM + eSIM connectivity helps reduce physical SIM swaps when equipment is moved, reassigned, or connected under a different carrier profile.
OEM Global Machinery
Standardise cellular connectivity for industrial machinery shipped into multiple markets. The R1520e Global combines broad LTE band support, industrial interfaces, and eSIM/eUICC profile management, helping OEMs reduce country-specific SIM logistics and support machines after delivery.
Global Retail & Branch Sites
Use the R1520e Global as primary or backup LTE connectivity for retail stores, branch offices, kiosks, and distributed enterprise sites. Remote eSIM provisioning helps central IT or managed service teams activate and change cellular profiles without shipping replacement SIM cards or sending technicians to site.
