Updated: Sep 8
Choosing between Teltonika FMC, FMB, FMT and FTC trackers? This guide compares the main 4G Teltonika GPS tracker families so fleet buyers can shortlist the right hardware for vans, cars, HGVs and Driver ID projects.

If you're searching for a reliable 4G GPS tracker for your UK fleet, Teltonika's FMC, FMB, and FTM product lines are among the most capable devices on the market today. Used by fleet operators, logistics companies, and telematics integrators across Europe, Teltonika trackers offer a combination of robust hardware, flexible connectivity, and deep configuration options that few competitors can match.
In this guide, we'll break down the key differences between the FMC, FMB, and FTM series, explain which device suits which use case, and help you make an informed purchase decision for your business.
Why Choose Teltonika for Fleet Tracking?
Teltonika Telematics has been producing GPS tracking hardware since 1998. Their devices are certified for use across Europe including the UK, and compatible with virtually every major fleet management platform — from Webfleet to Quartix and everything in between. Key reasons UK fleet managers choose Teltonika include: 4G LTE Cat 1 connectivity for fast, reliable data transmission; GNSS support covering GPS, GLONASS, BeiDou, and Galileo for accurate positioning; a flexible I/O system for connecting fuel sensors, temperature probes, and driver ID readers; remote configuration via SMS and GPRS; and over-the-air firmware updates.
Understanding the Teltonika FMB Series
The FMB series is Teltonika's most established hardwired line. The FMB130 and FMB140 are both 2G/GPRS devices rather than 4G — the 4G equivalents are the FMC130 and FMC140-class models — and the FMB140 and FMB130 each carry a 170 mAh internal backup battery so tracking continues even if the vehicle's power supply is cut. Both devices include digital and analogue inputs for tachograph integration, remote immobilisation, and driver identification via iButton or RFID. The FMB630 and FMB640 are premium options with CAN bus integration, giving direct access to engine RPM, fuel level, odometer readings, and fault codes without additional external sensors.
Exploring the Teltonika FMC Series
The FMC series is Teltonika's dedicated 4G Cat 1 hardwired line. The FMC130 is the most popular current-generation tracker: it features 4G LTE Cat 1 with 2G fallback, multi-constellation GNSS, an accelerometer for harsh driving detection, and a full set of digital and analogue inputs. Compact enough to conceal in a dashboard, it handles everything from basic location tracking to complex driver behaviour analysis.
The FMC640 adds RS232 and RS485 interfaces for direct tachograph integration, temperature loggers, and other specialist peripherals — ideal for refrigerated transport and coach operators. The FMC003 is a compact budget option for high-volume deployments where cost per unit matters.
When to Consider the Teltonika FTM Series
The FTM series takes a different approach: it is Teltonika's hardwired LTE Cat M1 fleet telematics line, built for low-power, long-life connectivity rather than tool-free fitting. If you want a plug-in instead, the FMC003 goes straight into the vehicle's OBD-II port for instant, tool-free installation. The FMC003 is ideal for car rental and leasing fleets where vehicles rotate frequently, SMEs that want tracking without professional installation downtime, insurance telematics applications, and pool vehicle management.
Choosing the Right Teltonika Tracker
For basic 4G hardwired tracking, the FMC130 is the best starting point. For advanced vehicle data via CAN bus, choose the FMC640 or FMB640. For plug-and-play OBD deployment, the FMC003 is ideal. For backup battery requirements, go with the FMB140. For high-volume cost-sensitive deployments, the FMC003 offers the best value.
Driver Identification with Teltonika Devices
Teltonika devices excel at driver identification. Using iButton readers or RFID/NFC keypads, fleet managers can assign every journey to a specific driver — critical for compliance, liability management, and accurate mileage reporting. Teltonika's open ecosystem supports driver ID accessories from multiple manufacturers, including Queclink keypads, making it straightforward to build a complete driver identification system.

FMC Series: Compact 4G Trackers for Modern Fleets
Teltonika's FMC series is designed for passenger vehicles, vans, and light commercial fleets where a compact, discreet unit is preferred. The FMC003 is the most popular entry point — an ultra-compact OBD-II plug-in tracker that requires no wiring and is operational within minutes. It reads vehicle diagnostics data directly from the OBD port, making it ideal for mixed fleets of cars and vans.
The FMC125 steps up with dedicated I/O ports for connecting external sensors, while the FMC234 adds a water-resistant casing with a high-capacity internal battery for exposed and off-power installations. At the top of the FMC range, the FMC640 supports CAN bus, RS232, and RS485 interfaces — making it suitable for HGV tachograph integration and specialist vehicle monitoring.
FMB Series: The Workhorse GPS Tracker for UK Fleets
The FMB series remains the backbone of Teltonika's commercial fleet offering. The FMB920 is the most widely deployed tracker in the UK — a compact unit with internal antennas and a wide voltage range, perfect for vans, cars, and light commercial vehicles. It has no 1-Wire pin, so driver ID on this model is done with a Bluetooth LE driver ID keypad rather than Dallas keys, making it a versatile choice for compliance-focused fleets.
For heavier vehicles and plant machinery, the FMB140 is the preferred choice. With external GNSS and GSM antenna connectors, it handles environments where signal penetration is poor — inside tipping trucks, under vehicles, and in agricultural machinery. The FMB003 rounds out the range as an ultra-compact OBD tracker in the FMB family, sharing the same firmware ecosystem.
All Teltonika devices are configured using the free Teltonika Configurator desktop software. Configuration profiles can be created, saved, and cloned across devices — making fleet-wide rollouts efficient. Parameters such as GNSS update frequency, movement detection thresholds, geofence settings, and I/O triggers are all set through the configurator.
For remote management, Teltonika's FOTA Web platform allows over-the-air firmware updates and configuration changes across entire fleets without physical access to the devices. This is particularly valuable for large fleets where attending to each unit individually would be impractical. Both tools are available free to authorised resellers and end users.
Which Teltonika Tracker Is Right for Your Fleet?
For cars and vans, the FMB920 or FMC003 offer the best balance of cost and capability. The FMC003 suits businesses that want a zero-installation plug-in option, while the FMB920 is the better choice where a hardwired installation or Bluetooth LE driver ID is needed.
HGV and truck operators should look at the FMB140 or FMC234 depending on antenna requirements. Plant machinery and agricultural operators benefit most from the FMB140's rugged antenna connectors and wide operating temperature range. Motorcycle fleet operators are best served by the FMT100, a purpose-built motorbike tracker rated IP65 — though it is a 2G device, so it sits outside the 4G range this guide covers.
