Spy Earpiece GSM
Choose a SIM earpiece kit by its microphone, receiver option and power setup. The GSM calling connection uses a SIM in the induction device. Match the selected model’s network bands to your local carrier, particularly for UK or US use. Compare SIM and phone connections before choosing your kit.
Choose the SIM kit, then check its network bands
A GSM kit uses its own SIM connection. Compare the card or piece arrangement, microphone and receiver option, then check the actual network bands against your operator in the country of use.
