Teltonika FMM650 — LTE Cat M1 Professional GPS Tracker with L1+L5 GNSS and Tachograph

The Teltonika FMM650 is the direct LTE Cat M1 and NB-IoT successor to the hugely popular FMM640 — the global IoT network version of Teltonika's most advanced professional tracker platform. Sharing the same comprehensive professional feature set as the FMC650 but on LTE Cat M1 and NB-IoT connectivity for broader international network coverage, the FMM650 is designed for the most demanding international fleet management, logistics, refrigerated transport and heavy duty transport applications where many types of external equipment need to be connected simultaneously and global network reach is essential.

Its dual-channel L1+L5 GNSS module provides positioning accuracy approaching RTK-grade equipment — significantly more accurate than standard single-band trackers and ideal for free flow electronic tolling system integration. A new more powerful processor, increased internal memory, switchable CAN terminators for multi-node CAN networks, Iridium satellite connectivity for remote area coverage and full support for Teltonika's DualCam and DSM video solutions complete a device that is in a class of its own for international professional telematics.

As an official Teltonika distributor in the UK, Tracking Hardware UK ships the FMM650 directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

Driver Identification with Tracking Hardware UK 1-Wire Keypad

The FMM650 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, tachograph and GPS data — providing complete driver accountability across international professional fleet deployments. Contact us to discuss keypad and FMM650 bundle pricing.

FMM650 vs FMC650 — Which Should You Choose?

The FMM650 and FMC650 are identical in professional features, interfaces and capabilities. The FMC650 uses LTE Cat 1 for faster data speeds on standard 4G networks — the recommended choice for UK and European professional fleet deployments. The FMM650 uses LTE Cat M1 and NB-IoT for broader global IoT coverage — the recommended choice for international deployments across EMEA, APAC and LATAM regions where Cat M1 infrastructure is preferred. Contact us for guidance on which best suits your deployment.
