GSM Frequencies

Tips for Purchasing GSM Spying Gear

Before purchasing any type of spying gear which uses GSM technology, it is important to ascertain the exact GSM frequencies which product uses for communication purposes. GSM vary significantly depending on where one lives. Therefore, if you choose a product which is not supported by your country’s GSM network system, the product will not operate.

GSM or Global Systems of Mobile Communications was first established in early 1970’s to provide a standard technology for the transmission of voice, digital and data communications to be used by mobile phones and other communications devices within a given region. Today, mobile devices within Europe utilize GSM frequencies 900 MHz or 1,800 GHz. However, North America mobile devices operate on GSM 850 MHz or 1,900 GHz frequencies.


Frequency: Measurement referring to number of times a specified periodic phenomenon occurs within a specified interval, also referring to completion of an electrical wave or cycle
MHz: Mega Hertz, a unit of frequency equal to one million cycles per second

Most countries today support GSM technologies compatible with their telecommunications network. GSM networking technology allows a myriad of mobile phones, laptops and data communications devices to operate. Many digital cellular subscribers worldwide depend on GSM networks. Anytime you send a SMS text, make a call or download data on a mobile or smart phone GSM technology is seamlessly handling the transfer and integration of your data communications data.

Like mobile phones, GSM spying gear also sends and transfers data using GSM frequencies. When reviewing specification for GSM related spying gear the product operational frequencies should be listed as 900 MHz / 1,800 MHz or 850 MHz / 1,900 MHz

If you live within Europe, Asia or Africa your GSM device will operate on GSM 900 MHz /1,800 MHz frequencies. However, if you reside in North America, USA, Canada or Mexico, the device will operate utilizing GSM frequencies 850 MHz/1,900 MHz only.

GSM spying gear which is based on North American GSM standards will not operate on GSM standards specific to Europe, Asia or Africa and vice versa. Therefore, it is important to note GSM frequencies of spying gear before purchasing to ensure the product will operate within your locale.

Types of GSM Spying Gear:

  • GSM spy cameras
  • GSM security or surveillance camera
  • GSM Audio Bugging Transmitters
Not all spying gear uses GSM communications technology. Those products which do utilize GSM technology will specify "GSM" either in the title description of product or within specifications of product. To clarify exactly which GSM network your country uses contact your local telecom service provider.

The most popular GSM networks are European including Asia, Australia, Africa and Middle East. However, if you live within Canada, USA or Mexico your product will operate on GSM 850 MHz/1900 MHz frequencies.

Note: There are some technical variances in frequencies bands which apply small number of countries outside of frequencies as mentioned. A dual band GSM device using 850/1800 will work in North America or Europe.

When purchasing GSM related spying gear read the product specifications, if available, before purchasing, to ensure your device will function properly within the continent or country you reside.
