How does GSW2 work?

GSW2 contains a normal mobile phone SIM card. When you call that SIM card as you would any normal mobile phone, GSW2 will check it's memory to see if you are an authorised User.

If you are, GSW2 will switch whatever you have connected it to & instantly hang up without answering the call. As GSW2 never actually answers the call , it doesn't cost anything to use it^.

If you are not an Authorised User, not only will GSW2 instantly reject the call but it will also log the unauthorised attempt to memory & send an SMS with the details (including the offending phone number) to the registered device Owner.

The GSW2 is  a multi-function control centre allowing you to control & moniter whatever you want with remote access to adjust the features by SMS text message from anywhere in the world.

^ Running Cost: Although you must maintain an active SIM card in GSW2, it costs absolutely nothing to use GSW2 unless you decide to use the SMS text alert feature in which case GSW2 will send you SMS text alerts as configured.
