911 Impacts of 3G phasing out

Posted by Janet Liebsch - November 02, 2021 10:04 AM

Regardless of cell carrier, there’s one universal number even deactivated phones have been able to traditionally dial: 911.

However, with the coming loss of 3G service, wireless customers won’t be able to dial 911 from any 3G phone including older style models of TracFones, flip phones, jitterbugs and others.

The nation's 911 call centers have no control once the 3G cell network shuts down and will NOT be able to dispatch emergency services to those who don’t have the ability to call them. This could impact swaths of rural communities without 4G or 5G options.

According to the FCC, mobile carriers are shutting down their 3G networks, which rely on older technology, to make room for more advanced network services, including 5G. As a result, many older cell phones will be unable to make or receive calls and texts, including calls to 911, or use data services. This will affect 3G mobile phones and certain older 4G mobile phones that do not support Voice over LTE (VoLTE or HD Voice).

There are also some other connected devices, such as medical devices, home security systems, and even rural credit card processing that may be impacted.

When is it happening?

Some places are already starting to feel impacts of 3G loss and many others could by January 1, 2022, though plans and timing to phase out services vary by company and may change. Consult your mobile provider's website for the most up-to-date information.

  • AT&T announced that it will finish shutting down its 3G network by February 2022.
  • Verizon announced that will finish shutting down its 3G network by December 31, 2022.
  • T-Mobile announced that it will finish shutting down Sprint's 3G CDMA network by March 31, 2022 and Sprint's 4G LTE network by June 30, 2022. It also announced it will shut down T-Mobile's 3G UMTS network by July 1, 2022, but has not yet announced a shutdown date for its 2G network.

If your mobile carrier is not listed here, you may still be affected. Many carriers, such as Cricket, Boost, Straight Talk, and several Lifeline mobile service providers, utilize AT&T's, Verizon's, and T-Mobile's networks.

Note: These are dates for completing the shutdowns. Carriers may begin retiring parts of their networks sooner.


What do I need to do?

Contact your mobile provider or consult your provider's website for more information about their 3G retirement plan and whether your phone, or other connected device, may be affected. It is important to plan now so that you don't lose connectivity, including the ability to call 911.

Some carrier websites provide lists of devices that will no longer be supported after 3G networks are shut down. You may need to upgrade to a newer device to ensure that you can stay connected, and carriers may be offering discounted or free upgrades to help consumers who need to upgrade their phones.

Some devices may only require a software update to enable VoLTE (HD Voice) or other advanced services. If you purchased your phone independent of a mobile provider, you should be able to check whether your device is 4G LTE (with VoLTE or HD Voice) enabled by checking your phone's settings or user manual, or by searching your phone's model number on the internet, to determine whether you need to purchase a new device or install a software update.

To determine if you have a 3G device, check your phone’s International Mobile Equipment Identity then visit www.imei.info or check with your local carrier.

Does this just impact phones?

No, other devices, such as certain medical devices, tablets, smart watches, vehicle SOS services, home security systems, and other connected products may be using 3G network services. And don't forget about devices that use cellular connectivity as a back-up when a wired internet connection goes down. If the device is not labeled, contact the monitoring company or other service provider to confirm how the device connects and whether your device may be impacted.

Why are 3G networks being phased out?

As mobile carriers seek to upgrade their networks to use the latest technologies, they periodically shut down older services, such as 3G, to free up spectrum and infrastructure to support new services, such as 5G. Similar transitions have happened before. For example, some mobile carriers shut down their 2G networks when they upgraded their networks to support 4G services. Mobile carriers have the flexibility to choose the types of technologies and services they deploy, including when they decommission older services in favor of newer services to meet consumer demands.
