Built for LPWAN IoT
LTE Cat M1 and NB-IoT deliver low-power, long-range coverage that's perfect for metering, sensors and telemetry, with 2G (EGPRS) fallback where newer networks aren't available.
Simple USB connectivity
Plug it into any host PC, gateway or embedded device over microUSB to add cellular internet in minutes — no separate power supply or complex wiring required.
Rugged & compact
An aluminium housing rated -40 °C to +75 °C with DIN-rail or flat-surface mounting makes it dependable in cabinets, plant rooms and harsh field sites.
Better signal where it counts
The external SMA antenna connector lets you position the supplied swivel antenna — or a high-gain alternative — for a stronger, more reliable link.
Is the TRM250 a router or a modem?It's a USB modem, not a router. It adds cellular connectivity to a host device (PC, gateway or embedded system) rather than creating its own Wi-Fi or LAN network.
What networks does it support?LTE Cat M1 and NB-IoT for low-power wide-area IoT, plus 2G (EGPRS) as a fallback on 850/900/1800/1900 MHz.
How does it connect and get power?A single microUSB port carries both data and 5 V power, so it draws everything it needs from the host — no external PSU required.
What operating systems work with it?Windows 7 to 10 (and Windows CE), Linux kernels 2.6 to 4.14, and Android 4.x through 8.x, using the supplied USB drivers.
Can I use my own antenna?Yes. It has a standard SMA connector, so you can fit the supplied swivel antenna or a high-gain external antenna for better signal.
What SIM does it take?A single Mini SIM (2FF) slot supporting 1.8 V and 3 V cards.
Is it suitable for industrial use?Yes. The aluminium IP30 housing is rated -40 °C to +75 °C and mounts on a DIN rail or flat surface for cabinet and field installs.
What's in the box?The TRM250 modem, an LTE swivel antenna (SMA male), a 0.8 m micro-USB cable, a hex key and the Quick Start Guide.
What warranty applies in Australia?The TRM250 carries a 2-year (24-month) warranty, backed by local Australian support.
