Interface Security Systems has identified all current customers across our entire footprint who could be impacted by AT&T sunsetting this network. The decision, targeted geography, timing and pace at which the 3G networks are sunset and shutdown are at the sole discretion of AT&T. We continue to work with our manufacturing partners to minimize any impact to our customers. If there is a known communication failure with your current panel and radio once the sunsetting takes place, we will contact you to review options that are available to you.
