Car GPS tracker: types, costs and how to choose

A car GPS tracker is a small device that works out its position from satellites and sends it over the mobile network to an app, so you can see where your vehicle is in real time. There are five types: Bluetooth tags, magnetic battery trackers, 2G SMS trackers, OBD 4G and hardwired 4G. To choose, look at four things: whether it sends its position in real time, how it is powered, which mobile network it uses and what it costs in total over the first year.

How a car GPS tracker works

A tracker does four things, one after another:

It finds its position
It receives signals from positioning satellites and knows where it is, to within about 5 metres outdoors.
It sends it
It has a SIM card and sends that position over the mobile network, just as a phone sends data.
A server stores it
The platform receives the positions, keeps the route history and checks your alerts (leaving an area, speeding, movement with the engine off).
You see it in the app
You open the app on your phone or computer and see the car on the map, its routes and its alerts.

That is why a real-time tracker needs two things: mobile coverage and a SIM with data. If there is no coverage for a while (an underground car park, an area with no signal), it stores the positions and sends them as soon as the signal returns.

A satnav is something else: it tells you where to go, but it does not send your position to anyone. A tracker does, so you can know where the car is even when you are not in it.

Types of car GPS tracker

Type	How it gets a position	Power	Real time	Installation
Bluetooth tag	Through other people’s phones passing nearby	Coin battery	No	None
Magnetic battery tracker	GPS + mobile network	Own battery, needs recharging	Yes, limited to save battery	Sticks on with a magnet
2G SMS tracker	GPS + SMS or 2G data	Own battery or cable	Limited	Varies
OBD 4G	GPS + 4G network	The car’s OBD port	Yes	Plugs in, no tools
Hardwired 4G	GPS + 4G network	Vehicle battery	Yes	Wired to the electrics

Bluetooth tag

The kind used for keys or luggage. It has no GPS and no SIM: its position is reported by nearby phones that detect it. In a busy town it can help you find a parked car; in open country or an empty car park it may give no position for hours. It does not alert you in real time if someone moves the car.

Magnetic battery tracker

It has GPS and a SIM and sticks to any metal part with a magnet. Its weak point is the battery: to last for weeks it sends few positions, and when it runs flat it stops working until you recharge it.

2G SMS tracker

The classic “no subscription” tracker: you put a SIM in it and it replies to an SMS with its position, or sends it over the 2G network. It only works while there is a 2G network in your area, and operators are switching it off (see 4G and 2G).

OBD 4G

It plugs into the car’s OBD port, usually under the steering wheel. Nothing to install, it is powered by the car and sends its position over 4G in real time. You can move it to another car in a minute. Most petrol cars from 2001 and diesel cars from 2004 have an OBD port.

Hardwired 4G

It is connected to the vehicle’s electrics and stays hidden. It is the hardest for a thief to find and also suits vans, lorries and motorbikes. It needs a simple installation.

Tracker with or without a subscription: what it really means

“No subscription” usually means one of these four things:

You pay for the SIM. The device has no subscription, but it needs a SIM with credit or a data plan that you buy separately from your network.
You pay per SMS. Every position request is a text message your network charges you for.
It is Bluetooth. There is no subscription because there is no SIM: and no real time either.
Some time included. The device comes with a few months or a year of service, and then you have to pay to keep using it.

Any tracker that sends its position in real time needs mobile data and a server that stores and shows it. Someone pays for that: you directly, or the manufacturer in exchange for a subscription.

With findCar the subscription is the plan: it includes the 4G SIM, flat-rate data, the platform, the route history for the last year and the app. No commitment: you pay for the period you choose and cancel whenever you like. From 3,99 € a month with the 2-year plan.

4G coverage and the 2G switch-off

A tracker needs mobile coverage to send its position. Two things worth knowing:

Choose 4G. 2G networks are being switched off across Europe. In the UK, operators have committed to switching off 2G by 2033 at the latest; in France it ends in late 2026 and in Germany in 2028 (information as of October 2026). A 2G device keeps working while any 2G network remains in your area, with less and less coverage. More in the shop comparison.
Better with several networks. A SIM that connects to several operators’ networks in each country has better coverage than one tied to a single company. findCar trackers work in 184 countries on several operators’ networks.

Installation: plug in or wire up

OBD 4G: one minute. Find the OBD port (usually under the steering wheel, to the left of the pedals), plug the tracker in and you are done. Step by step with video in the OBD 4G guide.
Hardwired 4G: simple installation. It is connected to the vehicle’s electrics (9–90 V). If you are not comfortable with car electrics, a garage can fit it quickly. Guide and video in the Tracker 4G guide.
Activation. Choose your plan in Activate, add the tracker in the app with its IMEI and it is active within 1 to 5 minutes.

How much a car GPS tracker costs in the first year

To compare, always add up both parts: the price of the device + what you pay to keep it working for the first year (subscription, SIM or SMS).

A cheap device with your own SIM can cost more over a year than one with a subscription, and a “no subscription” one may not give you real time. Compare the total, not just the device price.

Example with the findCar OBD 4G (prices in your currency):

Payment	Device (one-off)	Plan	Total
Paying monthly	See price	7,95 € a month	device + 12 months
Yearly plan	See price	59,95 € a year	device + yearly plan
2-year plan	See price	95,95 € (3,99 € a month)	device + 2 years

You pay for the device once and for the plan over the period you choose. 2-year warranty on the device.

What to check when choosing a GPS tracker: 8 points

Real time. Does it send its position on its own, every few seconds, or do you have to ask for it?
4G network. 4G is better than 2G, and several networks are better than one.
Position frequency. You should be able to adjust it; at 10 seconds you see the route in detail.
App and web. You should be able to see it on your phone and computer, and share it with other people.
History and alerts. Saved routes (for how long), zones with entry and exit alerts, speeding, movement while parked.
Battery when parked. It should have a power-saving mode so your car still starts. In power-saving mode the car battery lasts about 2–3 months with the tracker connected.
Warranty and returns. How many years of warranty and how many days to return it.
Commitment. Whether you must pay for a minimum number of months or can cancel whenever you like.

Is it legal to put a GPS tracker on a car?

It depends on who owns the car, who drives it and the laws of each country. A short guide:

Your own car, driven by you. Yes, tracking a vehicle you own is legal.
Your car, driven by other people (a family member, your partner). It is yours, but you are tracking whoever drives it: tell them there is a tracker.
Someone else’s car, without them knowing. No. Putting a tracker on another person’s vehicle to follow them without their consent may be a criminal offence, depending on the laws of each country.
Company vehicles driven by employees. Yes, within the law. In the EU and the UK, the GDPR and the UK GDPR require a legitimate and proportionate purpose, informing every employee beforehand and, where applicable, consulting employee representatives; regulators such as the UK ICO advise against constant monitoring. In other countries, such as the United States, the rules vary by state. More in Fleet tracking.
Rental cars. A rental company may track its vehicles if it tells the customer, usually in the rental agreement.

Car GPS tracker FAQ

What is the difference between a satnav and a GPS tracker?

A satnav guides you and does not send your position to anyone. A GPS tracker has a SIM and sends the car’s position to an app, so you know where it is even when you are not in it.

Where do you put a tracker in a car?

An OBD tracker plugs into the OBD port, usually under the steering wheel. A hardwired one is hidden inside the vehicle and connected to its electrics. Avoid placing it under large metal parts, which block the signal.

How can I tell if someone has put a tracker on my car?

Check the OBD port under the steering wheel, the underside and the bumpers (magnetic trackers stick to metal parts), the boot, under the seats and any extra wiring near the battery. If you find one that is not yours and think you are being followed without your consent, do not throw it away: go to the police.

Does a Bluetooth tag work as a car tracker?

To find a car parked in a busy area, sometimes. It is not real-time GPS: it only gives a position when a phone that detects it passes nearby, and it does not alert you if someone moves the car.

Does it need a SIM card?

A real-time tracker does. With findCar the SIM is already inside the device, set up, and the data is included in the plan: you do not have to buy or top up any SIM.

How often does it send its position?

It depends on the device. With findCar you set the frequency in the app; we recommend 10 seconds. When the car is parked it switches to power-saving mode to save battery.

Does it work abroad?

findCar trackers work in 184 countries and you can see them in the app from anywhere. They need mobile coverage to send their position.

What should I do if my car is stolen?

Report it, check its real-time position in the app and give it to the police. Do not try to recover the vehicle yourself.
