Description
DescriptionGSM-AUTO is a NEW USA AT&T 4G version wireless remote On/Off switch that can be controlled through a connection to the 4G/GSM cell phone network. The connection to the GSM cell network is accomplished by purchasing a SIM card and Pay-As-You-Go (PAYG) plan from your local wireless provider. Once the SIM card is installed in the SIM card holder on the top of the GSM module of your GSM-AUTO will have its own unique telephone number.The unit is activated by an incoming call to its cell phone number. The unit cannot answer a voice call but in sensing the call its logic will activate one or both of the output relays in a pre-programmed sequence. Because the unit doesn't answer the call, the activation of the relays does not incur any call charges to the PAYG plan or to the caller.Alternately, the individual relays can be activated by sending SMS text messages to the unit's phone number.
All the parameter settings can be done via 3 ways:iOS/Android APP software(highly recommended!), Computer software and edditing Mobile Messages.
