Our Simon XT would allow you to be notified of an alarm condition even if you had no phone.
You will need to add the cellular Module on to this system. This requires a monthly subscription to either our Mobile Pro or Total Home Service Plan. This will allow you to receive email notifications and text messages on alarm conditions. In addition to that, you will also be able to arm, disarm and check system status via web browser or smartphone. These systems provide alarm notification just as it would normally if you phone line was there.
