Teltonika RUT901 Industrial 4G LTE Dual SIM Router

Teltonika RUT901 – Dual SIM 4G Industrial Router

The Teltonika RUT901 (RUT901000600) is a compact industrial 4G LTE Cat 4 router with dual SIM, four Ethernet ports, and Wi-Fi. It is the direct successor to the RUT950 and RUT951. The RUT901 brings improved software, wider protocol support, and the full RutOS feature set in the same proven form factor. UK stock, next day delivery.

The defining capability of the RUT901 is automatic SIM failover. Two Mini SIM slots can switch between any two mobile networks based on signal strength, data limits, roaming status, or connection failure. No manual intervention is needed. Combined with wired WAN and Wi-Fi WAN options, the RUT901 supports four independent WAN sources – all configurable as automatic failover.

Applications

Primary Connection Failover for Fixed Broadband

The WAN port accepts a standard broadband connection via Ethernet. When that connection fails, the RUT901 switches automatically to 4G LTE. This failover is transparent to devices on the LAN. It is widely used in retail, hospitality, and branch office deployments where downtime directly impacts trading.

Industrial Automation and SCADA Telemetry

The RUT901 supports Modbus TCP Master and Slave, DNP3 outstation, and MQTT broker. These protocols allow it to poll industrial equipment, relay data to SCADA systems, and publish telemetry to cloud platforms. The digital I/O ports allow input monitoring and output switching triggered by configurable events.

Remote Site and Utility Infrastructure

Water treatment, electricity substations, and gas distribution sites frequently require continuous monitoring without fixed-line connectivity. The RUT901’s dual SIM allows pairing a primary network with a roaming backup SIM, maintaining connectivity if one carrier has a local outage. For inbound access to site equipment, a fixed IP SIM card removes the carrier-grade NAT barrier that blocks standard dynamic IP SIMs.

EV Charge Point Connectivity

The RUT901 is used to backhaul OCPP traffic from EV charge controllers to charge point management systems. The dual SIM failover keeps the OCPP session active if the primary carrier drops. The router’s compact footprint fits within most charge point cabinet configurations. The DIN rail mount is compatible with standard 35 mm rail.

Digital Signage and Retail IoT

A fixed IP SIM gives the RUT901 a static public IP, enabling remote access to display management systems and PoS hardware without VPN complexity. The three LAN ports support multiple devices on the same segment. Wi-Fi extends connectivity to handheld devices or customer-facing hardware without additional switches.

Temporary and Pop-Up Deployments

Events, construction sites, and temporary offices need fast connectivity without fixed-line lead times. The RUT901 powers from 9-30 V DC, accepts passive PoE input, and is rated to -40 °C. Both DIN rail and flat surface mounting options suit standard cabinet installations.

Frequently Asked Questions

Does the RUT901 support dual SIM?

Yes. The RUT901 has two Mini SIM (2FF) slots with external holders on the front panel. SIM switching is automatic and configurable across seven trigger conditions: weak signal, data limit, SMS limit, roaming, no network, network denied, and data connection failure. Both SIM slots are active simultaneously for monitoring; only one carries data at a time.

What is Teltonika RMS and is the RUT901 compatible?

Teltonika RMS (Remote Management System) is a cloud platform for monitoring, configuring, and updating Teltonika routers remotely. The RUT901 is fully compatible. RMS allows remote WebUI access, firmware updates across multiple devices, and alert notifications based on device status. See the Teltonika RMS explainer for more detail. RMS credits are sold separately.

What SIM card do I need for the RUT901?

The RUT901 takes Mini SIM (2FF) format in both slots. A SIM adapter kit is included in the box for Micro or Nano SIMs. For most applications requiring remote access or inbound connections, a fixed IP SIM is recommended – standard SIM cards sit behind carrier-grade NAT which blocks inbound connections. IoT and roaming SIM options are available from routerstore.com.

Is the passive PoE on the RUT901 compatible with standard PoE switches?

No. The passive PoE input on LAN1 operates at 9-30 V DC via spare pairs (Mode B). It is not compatible with IEEE 802.3af (48 V), 802.3at (48 V), or 802.3bt standard PoE. Connecting a standard PoE switch or injector operating at 48 V will damage the router. Use a passive PoE injector matched to 12 V or 24 V DC only.

Does the RUT901 support VPN?

Yes. RutOS includes OpenVPN (client and server, 27 encryption methods), IPsec (IKEv1/IKEv2, 14 encryption methods), WireGuard, ZeroTier, GRE, PPTP, L2TP, Stunnel, DMVPN, SSTP, and Tinc. Multiple VPN tunnels can run simultaneously. See the VPN on cellular routers explainer for guidance on choosing the right protocol.

Does the RUT901 support eSIM?

Not on this order code (RUT901000600). The standard UK variant uses physical Mini SIM cards only. eSIM-capable RUT901 variants exist – contact the team on 0300 124 6181 to confirm availability. For eSIM routers in stock, see the eSIM routers guide.
