The end of 2022 also marked the end of 3G networks for the three major cellphone carriers in the U.S.
Since Jan. 3, 2023, Verizon, T. Mobile, and AT&T are now relying on newer technologies, like 5G, to allow mobile devices, including security systems, to connect to the internet and transfer data. When an alarm is triggered for a security system that is still 3G-reliant, the alarm may not be communicated to the security provider.
To ensure no disruption in service and a proper response during an emergency, CPI proactively communicated and successfully upgraded the majority of customers before the 3G shutdown. In fact, 99% of CPI’s security systems have been upgraded or are not affected.
However, there are still several hundred customers who have not scheduled their FREE service upgrade, despite CPI’s repeated attempts to reach them. In fact, CPI has sent thousands of communications to ensure no customer experienced a disruption in service. CPI’s outreach included (numbers are approximate):
- 100,000 emails (As many as 20 emails per customer)
- Multiple outbound calls
- 20,000 SMS messages (As many as 4 text messages per customer)
- Hundreds of in-person visits to the home
It’s extremely important that anyone who hasn’t responded to CPI’s outreach do so now. Since 3G networks are no longer operable, CPI may not receive notification if an alarm is triggered in 3G reliant security systems.
While CPI is not responsible if your alarm system fails to function properly due to carrier network performance, CPI will upgrade your system communication to function with the carrier network at NO COST to you.

What is 3G?
3G is the third generation of wireless mobile telecommunications technology, which allows mobile devices to connect to the internet. It’s an upgrade from 2G and other technologies but has since been surpassed by 4G and 5G networks which offer faster and more robust service.
Why is 3G Shutting Down?
Mobile carriers now rely on newer technology that can serve more customers at higher speeds, using the same amount of spectrum. When newer technologies, like 5G, emerge, cellphone carriers will shut down older technologies to free up spectrum and infrastructure to support the new networks. **
When is the 3G shutdown?
As of January 3, 2023, AT&T, Verizon, and T-Mobile had all shut down their 3G networks.
Previously, the FCC released this of when the three major cellphone carriers expect to shut down their 3G networks on the following dates:
- AT&T announced it would finish shutting down its 3G network by February 2022. For more information, click here.
- T-Mobile announced Sprint’s older 3G network will shutdown on March 31, 2022.
- T-Mobile announced Sprint’s LTE network would retire on June 30, 2022.
- T-Mobile announced its older 3G UMTS network will shutdown on July 1, 2022. For more information on the T-Mobile 3G shutdown, click here.
- Verizon announced it will finish shutting down its 3G network by December 31, 2022. For more information, click here.
The timelines for the 3G shutdown will vary by company and may change. For the most up-to-date information, contact your mobile carrier.
Does the 3G Shutdown Only Affect Cellphones?
Keep in mind, the carrier on your CPI panel might be different than your cell phone provider.
No. The 3G shutdown will affect various devices that rely on 3G network services to connect to the internet and communicate information. The 3G shutdown can affect cellphones, certain medical devices, tablets, smartwatches, vehicle SOS services, home security systems, and other connected products. If you’re unsure if your device relies on 3G networks, contact the service provider to ensure you won’t lose service. *
