Are popular SIM-card GPS trackers 'adapters'? Check before you breach your operator's terms

In an era of widespread automation, more and more users are reaching for GPS trackers – small, cheap devices that, once placed in a vehicle, backpack or parcel, allow their location to be tracked in real time. These devices, available on a mass scale (e.g. on Allegro, Amazon or in Chinese shops), often require a SIM card to send data by SMS or GPRS. It is worth knowing, however, that such solutions – although seemingly simple and legal – may breach the telecommunications operator's terms of service and even lead to serious legal and financial consequences.

What is a GPS tracker and how does it work?

A popular GPS tracker (e.g. TK102, TK905, Coban, Wonlex) is a small device that:

• uses the GPS system to determine its location,
• has a GSM/GPRS module and a SIM-card slot,
• sends location data by SMS or data transmission (e.g. to a mobile app or a server).

It is most often used in vehicles, parcels, and even with elderly people or children. It works in the background – without user involvement – and can send its location, for example, every 30 seconds around the clock.

Is a GPS tracker an "adapter"?

The answer is not clear-cut. "Adapter" is not a statutory term — it is a term from operators' terms of service, used to describe devices that connect to the mobile network without human involvement (the M2M class). A GPS tracker with a SIM card is such an M2M device and may be subject to the provisions of a given operator's terms of service, so before use it is worth checking the tariff conditions — among other reasons because they:

• are not classic mobile phones,
• work in an automated way and without a user interface,
• generate repetitive, mass traffic on the mobile network (SMS messages, GPRS data),
• are difficult for the operator to manage remotely.

According to the terms of service of the largest operators in Poland (e.g. Polkomtel, Orange, Play), such devices qualify as adapters, whose use may depend on the operator's consent or the purchase of an appropriate M2M/IoT tariff — depending on the given operator's terms.

What are the consequences of illegal use?

Using an ordinary SIM card (e.g. with an "unlimited SMS" package) in a GPS tracker without the operator's consent may result in:

• the number being blocked and disconnected from the network,
• additional charges for misusing a consumer tariff,
• termination of the contract by the operator,
• the risk of breaching the provisions of the Telecommunications Law if the device is used in a way that threatens security or public order.

When a GPS tracker generates a huge amount of SMS messages or data, the network infrastructure may become overloaded, which in turn negatively affects the quality of services available to other users.

When is use legal?

In principle, to use a GPS tracker with a SIM card legally, you should:

1. Inform the operator about the type of device in which the SIM card will be used,
2. Obtain consent to use the card in an M2M-class device (adapter),
3. Choose an appropriate tariff intended for automated devices – the so-called M2M SIM or IoT SIM,
4. Ensure the device's security, i.e. its compliance with regulations and resistance to abuse (e.g. outdated firmware, susceptibility to attack).

Using popular GPS trackers with a SIM card in an unauthorised way, i.e. without the operator's knowledge and consent, may breach the terms of telecommunications services and lead to serious consequences – for both a private user and a business. A GPS tracker is not a toy – from a legal point of view it is an adapter, and its use should be conscious and compliant with the regulations.

If you are unsure whether your device or SIM card is being used in accordance with the regulations, contact a law firm specialising in telecommunications law or order a technical-and-legal audit of the system.
