Teltonika + SIMSY
Industrial cellular routers that run out of the box on SIMSY. Compact units for single-site deployments, full-feature gateways for complex ones, and a management platform that scales to the fleet.
Works out of the box
SIMSY SIMs activate on Teltonika routers with a one-line APN. No carrier wrangling, no custom scripts.
Industrial build quality
DIN-rail mountable, wide temperature range, extensive certifications. Built for sites that aren't a comfortable office.
Deep configurability
OpenWrt-based firmware with a familiar web UI, SSH, scripts, VPN clients, firewall rules — a real router, not an appliance.
Fleet management with RMS
Teltonika Remote Management System for monitoring and bulk configuration across a deployed estate — pairs well with SIMSY's own portal and APIs.
Routers built for the field
Teltonika Networks is a Lithuanian manufacturer of industrial networking hardware with one of the broadest cellular router portfolios on the market. Their devices run RutOS, an OpenWrt-based firmware familiar to any network engineer, and are backed by RMS — their fleet management platform — for configuration and monitoring at scale.
Hardware you trust, network you control
Teltonika deliver the hardware; SIMSY delivers the network behind the SIM. The combination gives you a cellular router that joins your own private network as soon as it powers on, with multi-network UK coverage, international roaming, and real-time control over addressing, routing and policy — all without touching the carrier side.
Insert SIM, set APN, done
Install the SIMSY SIM, set the APN in RutOS, and the router is on your SIMSY private network. From there you can push config through RMS, SSH in through the SIMSY Bridge for Tailscale, or expose services privately to the rest of your estate. Pre-flashed Teltonika kits with SIMSY SIMs are available for larger deployments.
Where this fits
EV charging
Compact Teltonika routers (RUT200, RUT240) with a SIMSY SIM give each charger a reliable connection to its back-office. Multi-network SIMSY SIMs keep sites online when a single carrier dips.
Digital signage
RUTX11 or RUTX50 at a signage endpoint — SIMSY delivers the private connection to your CMS, the Teltonika handles local Wi-Fi for staff and failover from fixed-line.
Remote industrial sites
Pump stations, substations, construction sites. Teltonika for the ruggedised hardware; SIMSY for the global multi-network connectivity that doesn't depend on a local ISP.
