3G is being phased out in North America and also at different places around the world and is being replaced with 4G. If your security system uses the 3G network, and you haven’t upgraded by the time AT&T and Verizon remove 3G functionality, your system will no longer be able to send alarm signals to our monitoring center. This means that, while an alarm may sound if a window or door is breached, our team won’t be alerted and will not be able to send assistance.
