3G/4G Sunset Information


Does your home or business security system operate via a third-generation (3G) or fourth-generation (4G) network? The time to upgrade this nearly obsolete technology is rapidly approaching. Due to the rapid increase in the demands on their wireless services, all the leading cell phone service providers are seeking ways to free up more bandwidth. As a result, they're transitioning to the faster signal capabilities delivered by long-term evolution (LTE) networks.


We recommend taking action well before your carrier's sunset date. Modernizing your security system with time to spare will help you prepare for emergencies during and after the transition that will phase out 4G home security systems. Contact your security system provider as soon as possible to discuss your situation and make arrangements to transfer to the updated LTE technology. Your provider should present a range of affordable options and help you make the best decision for your unique circumstances. Watch the webinar at the bottom of the page for more information on the 3G risks to your home or business after the sunset date.

FAQ - 3G/4G Communicator Sunset
The term "3G/4G sunset" describes the impending demise of these outdated technologies. All major cellphone carriers are constructing new towers and phasing out the older structures. If you're still using the older 3G or 4G networks to run your cellular-based security cameras, alarms, smoke detectors and other connected devices, your entire system could go dark soon. When this happens, you won't be able to protect your home or business.
When your security system registers that an event such as a fire or break-in occurs, it triggers a signal to a central monitoring station. There, monitors assess the situation and contact first responders if necessary. It's essential that you convert your system's alarm panel to an LTE network before the sunset date, so you can continue to communicate with the monitoring service. Making the switch also ensures that the station can support you when an emergency arises, so you and your family will have the resources you need.
The date that you can expect to lose your 3G or 4G access depends on your carrier. Each has listed the following sunset dates for their services:

AT&T: The AT&T 3G sunset date is February 22, 2022.

Verizon: If you're a Verizon user, the 4G sunset date is December 31, 2022. However, the carrier will shut down its 3G service by the end of 2020.

T-Mobile: While T-Mobile hasn't confirmed its 3G sunset date, most industry experts expect it to occur at the end of 2021.

Sprint: T-Mobile and Sprint have officially merged, but they will continue to operate as separate entities. Sprint will terminate its code​-division multiple access (CDMA) 3G networks on January 1, 2022.

Depending on your wireless network provider, you may have another year or two until the sunset date. However, you could see changes beforehand. For instance, Verizon Wireless discontinued activations and reactivations of 3G devices as of January 1, 2020. If you have a reliable, capable security system provider, it should monitor the situation and work with the device manufacturers to mitigate any issues during the transition.
