3G network phase-out: essential information for cellphone users

Mobile service providers in Canada and globally are actively phasing out, or have already phased out, their older third-generation (3G) cellular networks. As a result, some older cellphones may no longer be able to make or receive calls and/or texts, including emergency 9-1-1 calls, or use data services once your provider has phased out its 3G network.

Some international visitors could also be impacted if they attempt to roam on a Canadian provider’s 4G/LTE or 5G network using an older cellphone.

Electronic devices other than cellphones, such as home security systems, may also be affected.

Timing of the phase-out

The timeline for 3G phase-out varies by mobile service provider. Some providers have already completed their phase-out, while others have made public announcements or are still in the planning stages.

For the most accurate information, contact your provider regarding the status of its 3G network.

Some mobile providers operate affiliate brands and customers using these brands could also be affected:

Impact on your cellphone

Once 3G networks are phased-out, all voice calling will be done over Voice over LTE (VoLTE). VoLTE, which began to be implemented in Canada in 2015, improves call quality and supports enhanced calling features. As a result of the phase-out, older 3G cellphones may not work under VoLTE.

Your cellphone and/or SIM card will need to be upgraded if it falls under one of the following categories:

  1. Your cellphone exclusively functions on 3G networks.
  2. Your cellphone uses a 3G-only SIM card.
  3. Your cellphone does not support VoLTE (this may include older 4G devices as well)
  4. Your cellphone was not purchased through your provider and is not compatible with its 4G/LTE network.

Contact your mobile service provider for clarification on your cellphone’s compatibility.

Next steps

If you are impacted by the phase-out of a 3G network, your mobile service provider should contact you. However, if you have not been contacted and are concerned that your cellphone service will be affected, contact your mobile service provider or visit its website for more information. You can also check your cellphone’s user manual or search your phone’s model number online to determine its compatibility with newer networks.

If your cellphone is impacted, it will most likely need to be upgraded to a model compatible with newer networks. Your mobile service provider should be able to help facilitate this upgrade. Remember, if you do not upgrade your cellphone, you will be unable to use mobile services, including emergency 9-1-1 calling, once 3G networks are phased-out.

Other devices

Products such as tablets, smartwatches, medical alert devices, security systems, and other connected devices may be impacted by 3G network phase-out. Additionally, devices that use a 3G cellular connection as a backup for Internet access may also be affected.

Your device/service company should contact you if you are impacted. However, if you are not contacted and require clarification on whether your device will be impacted, contact your device/service company directly.
