How a SIM-based tracker differs from a Bluetooth tag or logger, and what to choose for your car, fleet, belongings or family.
If you need to see your car or fleet on a map in real time, get a tracker with a SIM card: only that type sends its location from anywhere with mobile coverage. A GPS tracker without a SIM card suits other jobs, such as finding your keys or bag nearby, or logging a route to review later. Also note that “no SIM” in adverts often means a built-in eSIM, so there is still a mobile connection.
How a GPS tracker with a SIM card works
The tracker gets its position from satellites and sends it over the mobile network (2G or 4G) to a server. You see the vehicle in the Navi.zone or Wialon app or dashboard: where it is now, which route it took and where it stopped.
Say you run a delivery van. The dispatcher sees it live, gets an alert when it leaves the city, and checks the mileage report in the evening. The SIM card needs mobile data for this, although a tracker uses very little.
These trackers come hardwired, as OBD plug-ins and as cigarette lighter units. Options for cars and vans are in our GPS trackers for cars section.
How a GPS tracker without a SIM card works
Several quite different devices are sold as “trackers without a SIM”. They work differently, so it is worth knowing what you are actually buying.
Bluetooth tags
A tag does not determine its own location. It sends a signal to nearby smartphones, and the phone reports where the tag was seen. In a city full of people that works. On a motorway, in a field or in a closed car park the tag can go silent for hours.
GPS loggers
A logger records the route to memory, and you view it after connecting to a computer or phone. Useful for sport or for checking a route after the fact. You cannot see the vehicle live or get a theft alert with one.
Radio trackers
These use their own radio channels and need a receiver or base station. It is a niche solution, for example on large farms where machinery works far from mobile coverage.
Trackers with a built-in eSIM
There is no separate SIM card, but there is a connection: it is built in and usually paid for as part of a subscription. In practice it is the same as a tracker with a SIM card.
Comparison: GPS tracker without a SIM card vs with one
| Feature | With SIM card | Without SIM card |
|---|---|---|
| Live tracking | Yes | No, or only near smartphones |
| Where it works | Anywhere with mobile coverage | Bluetooth: a few dozen metres; logger: no transmission |
| Alerts (geofences, movement, engine on) | Yes | No |
| Theft protection | Yes | Weak |
| Subscription | Connectivity and tracking platform | Usually none |
| Power | Vehicle power or rechargeable battery | Small built-in battery |
| Best for | Cars, fleets, machinery, trailers | Keys, luggage, belongings, sport |
Which one fits your task
- Fleet: vans, trucks, tractors. Only a tracker with a SIM card plus a fleet tracking platform. A farmer sees where the tractor is and how many hours it worked; a delivery business owner sees every van.
- Your own car, theft protection. A tracker with a SIM card, for example the Teltonika FMB920. The easiest start is the ready-to-use Teltonika FMP100 kit with a SIM card and Navi.zone, which plugs into the lighter socket.
- Keys, suitcase, backpack. A Bluetooth tag will do.
- Children or elderly relatives. Personal GPS trackers with a SIM card and an SOS button, used openly so the person knows about the device.
Tracking other people without their consent is illegal in Ukraine (Articles 163, 182 and 359 of the Criminal Code). Fit trackers to your own property; adult family members and employees must know about the tracker and agree to it, employees in writing.
How much it costs to run a tracker with a SIM card
There are two parts to the cost: mobile connectivity and the tracking platform. Platform prices:
- Navi.zone Base — from $9.90 per vehicle per year;
- Navi.zone Pro — 2,248 UAH per year for a bundle of up to 3 vehicles;
- Wialon Hosting — 195 UAH per month or 899 UAH for 6 months.
Connectivity costs depend on the operator and plan. Navi.zone is usually enough for one car; for a fleet with fuel sensors and reports, Wialon is the better fit.
FAQ
Does a GPS tracker without a SIM card work in real time?
No, there is no true live tracking without a mobile connection. A Bluetooth tag only shows a location when other people’s smartphones are nearby, and a logger only hands over the route once connected. If a listing promises live tracking with no SIM, the device most likely has a built-in eSIM paid for by subscription.
What SIM card does a GPS tracker need?
You need a SIM card with mobile data and reliable coverage wherever your vehicles travel. The PIN code is usually disabled, and a plan with a small data allowance is enough. If you drive abroad, check roaming in advance. Our article on choosing a SIM card for a tracker covers this in detail.
Will a Bluetooth tag protect my car from theft?
Only partly. A tag can show where the car was last seen if people with smartphones passed by, but it will not alert you to movement or a geofence exit. Stolen cars are often taken to deserted places where the tag stays silent. For real protection use a tracker with a SIM card, optionally with a standalone beacon as backup.
How much data does a GPS tracker use?
Not much: the tracker sends short packets with its position and sensor status. The volume depends on the reporting interval, the number of trips and the connected sensors, so check the actual figure after the first month. For a passenger car the smallest mobile data package is usually enough.
