Teltonika RUT981 – Global 4G LTE Cat 4 industrial router with Dual SIM, eSIM and WAN failover<\/h2>\n

The Teltonika RUT981 is a globally deployable industrial LTE router with 4G LTE Cat 4 connectivity (up to 150 Mbps download \/ 50 Mbps upload) and support for 3G and 2G. This IoT router combines Dual SIM with consumer type eSIM (up to 7 eSIM profiles, including profile download and removal) and supports eSIM bootstrap for initial profile download. For local integration, the router offers 4\u00d7 Ethernet ports (1\u00d7 WAN, 3\u00d7 LAN) and Wi-Fi 4 (802.11b\/g\/n) 2\u00d72 MIMO in Access Point (AP) and Station (STA) mode. The platform runs on RutOS (OpenWrt based Linux OS) and supports remote management via Teltonika RMS, WebUI, FOTA and more.<\/p>\n

 <\/p>\n

Why the Teltonika RUT981?<\/h3>\n

The RUT981 is relevant for organizations that want to combine global connectivity with scalable management and network continuity. With Dual SIM + eSIM and specified SIM switch auto-switch cases, the router can manage profiles and automatically switch in scenarios such as weak signal, data limits, roaming or connection problems. WAN failover and load balancing are included for distributing and securing connections in mission-critical infrastructure and industrial networking. For OT and IoT projects, the router supports multiple protocols and management options, making deployments centrally monitorable and maintainable.<\/p>\n

 <\/p>\n

Dual SIM, eSIM and failover for network continuity<\/h3>\n

The RUT981 features 2\u00d7 Mini SIM (2FF) and a consumer type eSIM with support for up to 7 eSIM profiles. eSIM functionality includes profile download and profile removal operations, with eSIM bootstrap for initial provisioning. In addition to SIM switching, the router supports network backup (Wi-Fi WAN, Mobile, VRRP and Wired options), WAN failover and load balancing. This allows the router to be deployed in environments where connections must continue to function when the primary route fails or where traffic is distributed across multiple WAN routes.<\/p>\n

 <\/p>\n

Industrial IoT and OT integrations with protocols and data-to-server<\/h3>\n

For IoT and OT network integration, the RUT981 supports multiple protocols and services commonly used in industrial environments. Specified include OPC UA (Client\/Server), Modbus TCP (Client\/Server, including custom registers and Modbus MQTT Gateway), DNP3 (Station\/Outstation) and DLMS\/COSEM (Client). For data exchange to platforms, the device supports Data to Server via HTTP(S), MQTT and Azure MQTT, including capabilities for custom LUA scripting. In addition, integrations are mentioned for IoT platforms such as Azure IoT Hub, AWS IoT Core, Cumulocity Cloud of Things and ThingWorx.<\/p>\n

 <\/p>\n

Security, VPN and network segmentation<\/h3>\n

The RUT981 includes comprehensive security and networking features within RutOS. For authentication, features specified include X.509 certificates, TACACS+ and internal\/external RADIUS, including IP and login attempt blocking and time-based login blocking. For network security, the platform supports firewall, NAT\/DMZ and configuration via WebUI or CLI, plus attack prevention features (including SYN flood protection and port scan prevention). For segmentation, VLAN (port- and tag-based) is included, and Wi-Fi security includes WPA2-Enterprise and WPA3 variants, including 802.11w Protected Management Frames (PMF). For secure connectivity, the router supports multiple VPN and tunneling options such as OpenVPN, IPsec, WireGuard, ZeroTier, DMVPN, L2TP\/PPTP, GRE and Stunnel.<\/p>\n

 <\/p>\n

Remote management and monitoring: RMS, WebUI, FOTA, TR-069 and SNMP<\/h3>\n

For remote management, the RUT981 supports multiple management methods. Teltonika RMS is available for remote monitoring and management, complemented by WebUI (HTTP\/HTTPS) for status, configuration, firmware updates and troubleshooting. Firmware management is also available via FOTA. For management in larger environments, TR-069 (with multiple ACS implementations) and SNMP (v1\/v2\/v3 + trap) are specified. Also included are SSH, JSON-RPC management API, MQTT broker\/publisher, SMS functions and call actions (such as reboot and status).<\/p>\n
