We guarantee a minimum of 36 activations within a period of 12 months. If the unit is tested once a month then the battery will last in excess of 2 years. If there are no activations the battery will last in excess of 4 years.
The device is configured very simply by sending the unit a configuration SMS from a mobile phone. Simply prepare the configuration SMS, press the test button to awaken the device and wait 60 seconds, then press send on the prepared configuration SMS.
The minimum top up is £10 and this provides 250 SMS text messages.
We currently use the O2 network. If you have no mobile coverage in your area then the device will not be able to communicate with the mobile providers and will not work. Please check www.02.co.uk/coveragechecker to see whether you have signal in your area.
