Teltonika FMM250

Teltonika FMM250 — IP67 Waterproof LTE Cat M1 GPS Tracker with Dual CAN and 100+ EV Models

The Teltonika FMM250 is the LTE Cat M1 and NB-IoT member of the Teltonika FMx250 series — Teltonika's most rugged and capable CAN tracker family. Building on the proven FMx150 platform and adding an IP67 waterproof enclosure, the FMM250 combines all the dual CAN intelligence, multi-protocol support and broad vehicle compatibility of the FMC250 with LTE Cat M1 and NB-IoT connectivity — making it the ideal choice for large-scale international fleet deployments in harsh environments where IoT network infrastructure is preferred.

Like the FMC250, the FMM250 supports over 100 electric vehicle models — one of the most comprehensive EV coverage profiles of any tracker in the Teltonika range. Combined with dual CAN channels, LV-CAN200, ALL-CAN300, J1939, FMS and tachograph data reading, 1-Wire, Bluetooth 4.0 and both micro SIM and eSIM support, the FMM250 is a complete solution for agriculture, construction, mining, heavy transport and electric vehicle fleet operators who need IoT network connectivity and waterproof durability in a single device.

As an official Teltonika distributor in the UK, Tracking Hardware UK ships the FMM250 directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

Key Features

• LTE Cat M1 and NB-IoT with 2G fallback — low-power wide-area IoT network connectivity offering broader global coverage and lower power consumption than standard LTE, with NB-IoT support and automatic 2G fallback ensuring continuous operation

• IP67 waterproof and dustproof — fully sealed enclosure rated to IP67, dust tight and protected against temporary water immersion — safe for outdoor mounting, pressure washing and operation in mud, rain and extreme conditions

• Dual CAN channels — two independent CAN interfaces for simultaneous reading from multiple vehicle systems, providing broader and more accurate fleet data than single-channel devices

• Over 100 electric vehicle models supported — one of the most comprehensive EV profiles in the Teltonika range, reading battery level, charging status, remaining range and EV-specific parameters across 100+ models

• Multi-protocol CAN support — simultaneously supports LV-CAN200, ALL-CAN300, J1939 for trucks and agriculture, FMS for commercial fleet management and OBD-II for diagnostic data Tachograph data reading — reads digital tachograph data for driver hours monitoring and commercial vehicle compliance reporting

• Micro SIM and eSIM — supports both a physical micro SIM and a built-in eSIM for flexible connectivity options across UK and international IoT deployments

• 1-Wire interface — connects temperature sensors for cold chain and refrigerated transport monitoring and iButton for driver identification

• Bluetooth 4.0 — connects to BLE sensors and supports wireless accessory integration

• Remote immobiliser — digital output allows remote vehicle disabling via your fleet management platform

• Crash detection — built-in accelerometer detects and records impact events

• Jamming detection — alerts when GPS signal interference is detected

• Green driving monitoring — tracks harsh braking, acceleration and cornering for driver behaviour scoring

• Excessive idling detection — monitors prolonged engine idling for fuel cost reduction

• Backup battery — 170mAh Li-ion maintains device operation if vehicle power is cut

• Over-the-air updates — firmware and CAN OEM files updatable remotely via FOTA Web

Driver Identification with Tracking Hardware UK 1-Wire Keypad

The FMM250 supports 1-Wire connectivity and is fully compatible with the Tracking Hardware UK 1-Wire driver identification keypad. Drivers enter their unique PIN at the start of each trip and the driver ID is logged alongside all CAN data, GPS and telematics information — giving fleet managers complete driver accountability across harsh environment and international fleet deployments. Contact us to discuss keypad and FMM250 bundle pricing.

FMM250 vs FMC250 vs FMB240 — Which Should You Choose?

All three devices share the same IP67 waterproof housing and integrated CAN processor. The FMB240 uses 2G GSM and supports 40+ EV models. The FMC250 uses LTE Cat 1 and supports 100+ EV models — the recommended choice for most new UK deployments. The FMM250 uses LTE Cat M1 and NB-IoT with 100+ EV support — the best choice for large-scale international deployments targeting IoT network infrastructure, where broader global coverage and lower power consumption are priorities.
