Teltonika FMM920 — Best-Selling LTE Cat M1 Compact GPS Tracker for Global Fleet Deployments

The Teltonika FMM920 is Teltonika's best-selling LTE Cat M1 GPS tracker — the global IoT network member of the FMx920 family, sharing the same proven compact form factor, Bluetooth 4.0 connectivity and feature set as the FMB920 and FMC920 but on LTE Cat M1 and NB-IoT technology for broader international network coverage.

Where the FMC920 uses LTE Cat 1 for faster data speeds on standard 4G networks — the recommended choice for UK and European deployments — the FMM920 uses LTE Cat M1 and NB-IoT with 2G fallback, providing broad global IoT network coverage across North America, Asia Pacific, Latin America and other international markets where Cat M1 infrastructure is preferred. This makes the FMM920 the natural choice for telematics service providers and fleet operators deploying at international scale across multiple regions from a single hardware variant.

As an official Teltonika distributor in the UK, Tracking Hardware UK ships the FMM920 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 — global IoT network connectivity across a broad range of international LTE bands covering North America, Europe, Asia Pacific and Latin America, with NB-IoT support and automatic

• 2G fallback for continuous coverage

• Compact form factor — same 79 x 43 x 12mm ultra-compact design as the FMB920 and FMC920, enabling easy installation and concealment in virtually any light vehicle

• Bluetooth 4.0 + BLE — connects to EYE Sensors for temperature, humidity and cargo monitoring, EYE Beacons for traceability and wireless driver identification accessories

• 170mAh Li-ion backup battery — maintains device operation and data logging if vehicle power is cut, essential for tamper and theft detection scenarios

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

• Crash detection — built-in accelerometer detects and records impact events for accident reporting and insurance evidence

• Tow detection — triggers alerts when the vehicle is moved without ignition

• Unplug detection — alerts when the device is disconnected from vehicle power

• Jamming detection — alerts when GPS signal interference is detected for anti-theft applications

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

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

• GNSS fuel counter — estimates fuel consumption via GNSS-based calculation

• Auto and manual geofencing — automatic geofence at ignition off location plus configurable zone alerts

• Multiple sleep modes — GPS sleep, online deep sleep, deep sleep and ultra deep sleep for optimised power management

• 128MB internal memory — stores up to 422,400 records when out of network coverage

• Over-the-air updates — firmware updatable remotely via FOTA Web

Driver Identification with Tracking Hardware UK BLE Keypad

The FMM920 supports Bluetooth 4.0 and is fully compatible with the Tracking Hardware UK BLE driver identification keypad. Drivers enter their unique PIN or present their card at the start of each trip and the driver ID is logged alongside all GPS and telematics data — giving fleet managers complete driver accountability across international fleet deployments. Contact us to discuss keypad and FMM920 bundle pricing.

FMM920 vs FMC920 vs FMB920 — Which Should You Choose?

All three share the same compact form factor, Bluetooth 4.0, backup battery, remote immobiliser and feature set. The FMB920 uses 2G GSM — cost-effective for stable 2G coverage and shorter deployments. The FMC920 uses LTE Cat 1 — the recommended choice for UK and European deployments requiring fast 4G data. The FMM920 uses LTE Cat M1 and NB-IoT — the recommended choice for international deployments across North America, Asia Pacific and Latin America where Cat M1 IoT infrastructure is preferred. For UK deployments the FMC920 is the recommended choice. For global multi-region deployments the FMM920 is the better fit.

Frequently Asked Questions

What is the difference between the FMM920 and the FMC920?

Both share the same compact form factor, Bluetooth 4.0, backup battery and features. The FMC920 uses LTE Cat 1 for faster data on standard 4G networks — recommended for UK and European deployments. The FMM920 uses LTE Cat M1 and NB-IoT for broader global IoT coverage — recommended for international deployments across North America, Asia Pacific and Latin America.

What is the difference between the FMM920 and the FMB920?

The FMM920 uses LTE Cat M1 and NB-IoT for global IoT network connectivity. The FMB920 uses 2G GSM. For new deployments the FMM920 is the more future-proof choice. For cost-sensitive 2G deployments in stable coverage areas the FMB920 remains an option.

Is the FMM920 compatible with the Tracking Hardware UK BLE driver identification keypad?

Yes — the FMM920 supports Bluetooth 4.0 and is fully compatible with the Tracking Hardware UK BLE driver identification keypad. Contact us for keypad and FMM920 bundle pricing.

Does the FMM920 need a SIM card?

Yes — the FMM920 requires a SIM card with LTE Cat M1 or NB-IoT capability and 2G fallback. It is not supplied with a SIM. Contact us for SIM recommendations for UK and international fleet deployments.
