3G/4G Upgrade Program

Throughout the St. Louis area, Central and Southern Illinois, and around the country, cellular carriers such as Verizon & AT&T are in the process of discontinuing 3G wireless cellular service. This change will eventually result in an interruption in our security monitoring services. This technology change is not just impacting PASS Security. It is impacting all alarm monitoring service providers nationwide.

We are required to upgrade your security systems cellular communicator to support the newer LTE and 5G service to avoid an interruption in services.

What does this mean and how does it affect my system?

Your security system currently uses a cellular communicator that uses AT&T or Verizon 3G type cellular services to notify our monitoring center in the event of an alarm. Like many cell phones, your alarm system needs to be upgraded from time to time to handle the faster speeds and newer technology released by cellular providers.

What ACTION is REQUIRED and what are my options?

A large percentage of our customer base is impacted and will require the communicator to be replaced prior to the deadline given by AT&T and Verizon. We at PASS Security are taking a proactive approach to ensure we can get your cell communicator replaced before the deadline to avoid service interruptions caused by cellular providers.

We have two different options below:
