3G Sunset

Cellular carriers such as AT&T, Verizon and T-Mobile are phasing out older 3G networks to allow for advanced technology such as 4G/5G and LTE.

With carriers ending the support of the 3G network, alarm systems currently operating on 3G technology will no longer be able to communicate with our monitoring center over the cellular network.


What does this mean for you?

Your system may be affected by the 3G sunset and it is very important that you contact us as soon as possible to avoid service disruption.

If you have received a letter, phone call or email about upgrading your system, please complete the request form below to schedule service.

Why are carriers phasing out the 3G network?
In an effort to keep up with the increasing demands of the modern consumer, carriers are phasing out 3G networks in favor of faster and more advanced technology found in 4G (LTE) and 5G networks. These networks are much faster and provide superior coverage compared to the expiring 3G networks, which were built for basic needs and only provide for limited data transfer. For this reason, carriers have announced they will soon stop supporting the older technology all together.
What does 3G technology have to do with my security system?
In the event of an alarm, there are currently three ways your alarm system is able to communicate to our monitoring center 1) over the internet 2) over a landline 3) using a cellular transmitter. If you have power at home and your internet/phone lines are working properly, then your alarm system can communicate to the monitoring center using those methods; however, in the event your internet is down and/or power goes out, the cellular transmitter would serve as a backup by providing communication over the same networks as your cell phone (3G/4G/5G LTE networks). If your alarm is using an old 3G transmitter after the network is phased out and your alarm is triggered when you have no power or internet, the alarm may audibly sound in your home but it will be unable to properly communicate to the monitoring center in the event of an emergency.
How do I know if I'm affected?

If you are unsure if your system currently operates on the 3G networking and have not received any communication from us regarding the need to upgrade your system, you can call us to verify if your system will be affected by the 3G Sunset.

When do I need to upgrade?

Some carriers have already begun to phase out the 3G network in some areas and most carriers will fully stop supporting 3G devices by early 2022. We recommend acting sooner rather than later to ensure there is no lapse in coverage for your service.

Am I charged for this?

We are offering updated equipment and installation to customers with two payment options:

1) A one-time, no committment payment.

2) Subscribe to our Cell Upgrade Program for no money down and a low monthly payment. Selecting this option will protect you against future cellular sunsets and requires a signed 36 month agreement.

Select your preferred upgrade option below in the Service Request Form.

Can I upgrade my 3G cellular communicator myself?

At this time, there is not a do-it-yourself option, however our experienced technicians are here to help you through this transition.
