Teltonika FMC920 vs FMB920: which tracker for vans and cars?

These are the two trackers we are asked about most often, and it is easy to see why. They are the same size, they fit the same way, they do the same job on the map — and one is cheaper. The honest answer is that the price gap is not the thing that should decide it.

The short version

Buy the FMC920 (£25.00 inc VAT) if the vehicle will still be on your fleet in 2030. Buy the FMB920 (£19.99 inc VAT) only if it will not.

The part most comparisons leave out: 2G is going away

Every UK network has already switched off 3G. 2G is next, and the dates are published:

  • EE — 2G switch-off begins May 2029
  • O2 — switch-off begins summer 2029
  • Vodafone — during 2030

That matters more than any feature on the spec sheet. A 2G-only tracker fitted today has a working life measured against those dates, not against the hardware warranty. If the vehicle will still be on the fleet in 2030, the cheaper device is not the cheaper decision — you pay for the unit twice, plus the fitting labour twice.

Where 2G still makes sense: short-term hire fleets, vehicles due for disposal inside three or four years, and low-value assets where a replacement in 2029 is simply accepted. Everywhere else, buy 4G.

What they share

Both are hardwired units for 10–30 V vehicles, so cars, vans, motorbikes and light commercials are all in scope. Both give you live tracking, route history, geofences, towing detection, overspeed alerts and driver behaviour scoring, and both support remote immobilisation when it is wired in at fitting. On the Fleetalyse map you cannot tell which is which.

Both also carry the same single set of inputs and outputs. If you need more than one digital input — a PTO, a door sensor and an alarm at once, say — neither of these is the right unit and you want something from the asset and trailer range or the FMC650.

Where the FMC920 pulls ahead

Beyond the radio, the FMC920 adds the fuller satellite picture — Galileo and BeiDou alongside GPS and GLONASS — which shows up as a faster first fix and steadier positions in cities where the sky is half blocked by buildings. The IP54 rating also means it survives a mounting position that is not perfectly dry, which matters more on vans than anyone admits at fitting time.

Where the FMB920 is still the right call

At £19.99 it is genuinely cheap, and for a vehicle heading for auction in two years the 2029 dates never arrive. Short-term hire fleets, seasonal vehicles and low-value assets are all reasonable homes for it. Just make the decision deliberately rather than by price alone.

Buying either one

Both are sold two ways. The Fleetalyse-ready version arrives with a 4G global IoT SIM and is ready to report the day it is fitted. The unlocked version has no SIM and no platform lock, so you can run it on your own system — and if you later change your mind, an unlocked unit can still join the Fleetalyse platform through bring your own device.

Platform subscriptions start at £5.99 per device a month including VAT, with full API access on every tier. Ordering three or more units takes a quantity discount off the hardware automatically.
