Teltonika FMM250
Teltonika FMM250 — IP67 LTE Cat M1/NB-IoT tracker with dual CAN processor supporting 100+ EV models, J1939 and FMS. Official Teltonika UK distributor.
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 — check the rated installation conditions; IP67 does not establish pressure-washing suitability
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. Contact us for guidance on which best suits your deployment.

Frequently Asked Questions
What is the difference between the FMM250 and the FMC250?
The FMM250 and FMC250 share the same IP67 housing, dual CAN processor, 100+ EV support and feature set. The FMC250 uses LTE Cat 1 for faster data on standard 4G networks — the recommended choice for most UK fleet deployments. The FMM250 uses LTE Cat M1 and NB-IoT for broader global IoT coverage and lower power consumption — better suited for large-scale international deployments or IoT network infrastructure.
Does the FMM250 support electric vehicles?
Yes — the FMM250 supports over 100 electric vehicle models, reading EV-specific parameters including battery state of charge, charging status and remaining range. It is one of Teltonika's most capable EV-supporting CAN trackers.
Is the FMM250 compatible with the Tracking Hardware UK 1-Wire driver identification keypad?
Compatibility must be checked for the exact tracker and keypad models, interface, firmware and configuration. Bluetooth support alone does not confirm BLE keypad compatibility, and wired keypads require a supported wired interface. Send us the proposed pairing for a compatibility check before ordering.
Can I buy the FMM250 in bulk from Tracking Hardware UK?
Yes — we supply telematics service providers, fleet operators and resellers across the UK and internationally. Volume pricing and trade accounts are available. Contact us for a bulk quote.
Do you hold UK stock of the FMM250 and do you ship worldwide?
Contact Tracking Hardware UK to confirm current stock, dispatch time and a delivered quote for your quantity and destination. We supply B2B customers internationally.
Is the FMM250 locked to a specific platform or SIM card?
Confirm that your platform supports this exact model and its required protocol and features. Where a cellular SIM is used, the SIM plan, supported bands, operator coverage and device configuration must match the deployment.
