The R600 SIM GSM Ear is a cellular listening device or "bug" manufactured by First Electronics in Taiwan. You call the number assigned to the inserted SIM card, and the R600 automatically answers without ringing. You can then listen to what's being said in its vicinity. The R600 can only use SIM card-based GSM cellular networks, such as AT&T and T-Mobile.
