Protect your data

Keep confidential information safe

As mobile devices and personal computers are being used to do more each year, it is important that you take the necessary steps to protect your personal and confidential information. Below are just some of the steps you can take to protect your data. More information on protecting yourself can be found at

Passwords are a must

  • Make sure that your device is password protected. 
  • Ensure that the password, passphrase or PIN that you use is strong and cannot be easily guessed. 
  • Configure your settings to ensure that your device locks after a short period of time. 

Keep track of important information 

  • For mobile devices, have your IMEI (International Mobile Equipment Identity) number written down or stored somewhere safe (you may access this number by typing *#06# into your device or by looking on the back of your device behind the battery). 

Software security is critical 

  • Keep device and computer software up to date. This will ensure that the security features are working to their maximum capabilities. 
  • Do not remove or alter any of the manufacturer’s security features. 
  • Do not install any illegal software or software that does not come from a trusted source. For more information software used by cyber criminals to infect systems and devices and steal information, click here.

The right app can help 

  • Consider using an application that will allow you to locate and remove/erase data from your device remotely in the event of loss/theft. 
  • Review all requests for access permissions carefully when installing applications and software. 

Keep your eyes open for red flags 

  • Do not click on any links in emails or text messages that seem suspicious, including emails or messages from someone that you do not know or that you were not expecting. For information on the types of emails and message to look out for click here.
  • Beware of unsolicited calls, texts, or emails where the caller or sender asks you for personal information, including your name, address, birthdate, Social Insurance Number (SIN), or your credit card or banking information. If you receive an unexpected call or message alleging to be from your bank, law enforcement or a government agency, do not provide your personal information and instead hang up and make an outgoing call to the relevant institution (using the contact information on their website, not the information provided during the call or in the message) to determine if the call or message you received is legitimate.  
  • For more information on protecting yourself from scams and frauds visit the Canadian Anti-Fraud Centre website here.

Usage tips 

  • Clear the device of all personal data when recycling your cell phone or computer.  
  • When using your mobile device or computer to log on to websites, make sure that you completely log out after each session. 
  • Use only secure Wi-Fi networks. 
  • Turn off Wi-Fi and Bluetooth connections when not in use. 

Watch out for “shoulder surfing” 

  • When using your device or computer, look out for people staring over your shoulder. Use the same precautions that you would employ at an ATM and shield your device. 

Always have a backup plan 

  • Back up important files and information that you wouldn’t want to permanently lose. 
  • Check out device insurance options with your wireless service provider. 

5G and aviation

Facts about 5G and aviation in Canada

There have been media reports of concerns in the United States regarding the potential for interference between radiofrequencies used for 5G and the operation of aircraft radio altimeters.

The following sets out the facts regarding the situation in Canada:

  • Radio altimeters are instruments used in aircraft to measure distance from the ground (altitude). They are authorized to operate in the 4200-4400 MHz spectrum band.
  • Recent media reports in the United States relate to spectrum being used for 5G in the 3700 to 3980 MHz frequency band (within the so-called C-Band). This band is currently not authorized for use with cellular services in Canada.
  • In Canada, cellular services have been authorized to operate in the 3450-3650 MHz range (also referred to as the 3500 MHz band). This means that the 3500 MHz band is separated by at least 550 MHz from the frequencies used by altimeters, thus providing ample separation.
  • This “buffer zone” is twice the amount of separation provided by the C-Band used in the United States. It is also over 100 MHz more separation than in Europe, which uses the 3400-3800 MHz range of the C-Band for 5G services.
  • Internationally, C-Band spectrum is already being used in nearly 40 countries and hundreds of thousands of 5G base stations with no reported incidents impacting aviation. This includes, for example, Japan, where the separation is only 100 MHz.
  • The 3500MHz band has been safely used in Canada for years for fixed wireless communications.
  • Recent statements from regulators around the world have confirmed the lack of reported incidents of interference from C-Band spectrum impacting aircraft radio altimeters:

    • UK regulator Ofcom: “We can’t comment on how airwaves are allocated by authorities in other countries. But in the UK, 5G and other mobile services have been used in airwaves alongside altimeters for some years with no reported cases of interference in UK airspace.” 
      See statement here.

    • Norway’s Telecom Regulator (January 2022): “The 5G networks now being developed in Norway and Europe use lower frequencies than in the US and other parts of the world. The frequencies we use have a greater distance from those used in the altimeters in aircraft, and we therefore do not have the same problem”. In addition, it also states: “authorities are not aware on reported interference from 5G to the altimeters, and 5G deployment has been ongoing for several years in Europe and the rest of the world. In Japan where they currently use frequencies closest to the altimeters, tens of thousands of 5G base stations have been taken in use. As far as Nkom is aware, no interference has been reported there”. 
      Full statement here.

    • U.S. Federal Aviation Administration (May 2023 Bulletin): “There have not yet been proven reports of harmful interference due to wireless broadband operations internationally, although this issue is continuing to be studied. In the United States, there has been wireless broadband deployment in the 3.65-3.7 GHz band since 2007. The FCC started a proceeding to authorize mobile broadband service in the 3.55-3.7 GHz band in December 2012 and adopted final rules in April 2015 and October 2018. Commercial deployment started in September 2019, with no known issues for altimeters to date.” 
      Full statement here.

    • European Union Aviation Safety Agency (oversees civil aviation in 31 EU countries): “The technical data received from EU manufacturers offers no conclusive evidence for immediate safety concerns at this time… EASA is not aware of any in-service incidents caused by 5G interference.” 
      See quotes here.

    • German Federal Telecom Regulator (January 2022): underlines how measurements carried out in France and Norway “have shown that there has been no concrete influence on the instruments so far”. 
      Reports here.

  • Notwithstanding the absence of any reported instances of interference in other countries and the larger separation between the 3500 MHz band and the frequencies used by altimeters, the Government of Canada has, out of an abundance of caution, imposed restrictions regarding the use of 3500 MHz spectrum in the vicinity of airports, as well as requirements regarding the positioning of antennas across the country (see:
  • The government has indicated that these rules may be amended pending further study and testing.
  • Canada’s wireless industry continues to work with the government and aviation industry to further study this issue and ensure that any rules regarding the use of spectrum are evidence-based.

U.S. mobile carriers discontinuation of 3G/HSPA network service

Starting in February 2022, U.S. carriers will be phasing out their 3G/HSPA wireless network service in the U.S. (including Puerto Rico and the U.S. Virgin Islands). This discontinuation of service will impact Canadian mobile wireless subscribers who are travelling in the U.S. and are using a mobile device that does not support 4G LTE data and Voice over LTE (VoLTE) roaming.

This FAQ is provided for general information purposes only and is current only as of the published/updated date indicated below. For specific questions about how the U.S. 3G network service discontinuation may impact you please check your service providers support web pages or contact you service provider directly.


What is a 3G wireless network?

3G/HSPA refers to a third generation of wireless access standards that allows mobile devices to connect to the internet and to place and receive voice calls. 3G was introduced in the early 2000s and has been followed by 4G LTE and, most recently, by the newest generation of wireless standards, 5G.

When will the U.S. carriers be discontinuing their 3G network services in the U.S.?

AT&T has announced that its 3G/HSPA network service will be discontinued by February 2022.

T-Mobile has announced that its 3G/HSPA network service will be discontinued as of July 1, 2022.

Verizon uses a different 3G standard, known as CDMA. CDMA is no longer supported by Canadian wireless service providers so the shutdown of its CDMA network, also expected to be in 2022, will not impact Canadian mobile wireless subscribers.

I am a subscriber to a Canadian wireless service provider, why should I be aware of U.S. 3G network service discontinuation?

When travelling in the U.S. (including Puerto Rico and the U.S. Virgin Islands) Canadian subscribers are able to connect to the internet and make and receive mobile voice calls by accessing the mobile wireless networks of U.S. service providers. This is referred to as “roaming”.

If your mobile device only supports 3G/HSPA network access, you will not be able to use voice services and you will be unable to connect to the internet and use mobile data services on AT&T and T-Mobile networks once their 3G network services are discontinued. If you have a 4G LTE device that does not support Voice over LTE (VoLTE) roaming, you will not be able to make or receive voice calls on AT&T or T-Mobile mobile networks.

Provided you have a compatible device, wireless services will continue to be available on U.S. carrier 4G LTE and 5G networks when roaming in the U.S.A.

See “Based on my device type, what services are impacted by the 3G network discontinuation?” below for more details.

How can I determine if I am on AT&T or T-Mobile’s 3G / HSPA network when roaming?

Near the battery icon on the display screen on most mobile devices there will be a 3G / HSPA network identifier shown when connected to a 3G/HSPA network. You will typically see an LTE or 4G carrier network identifier if you are using a 4G LTE-capable device and connected to a 4G LTE network.

What is Voice over LTE (VoLTE) Roaming?

Voice over LTE (VoLTE) allows customers with a compatible phone to place and receive voice calls over a 4G LTE network instead of a 3G/HSPA network. VoLTE enables faster call connection times and improved voice quality service. VoLTE roaming is placing and receiving voice calls while accessing the network of a service provider that is not your home service provider. Check your 4G LTE compatible mobile device specifications to confirm it supports VoLTE roaming. If you have an older LTE device, you may need to update your device software.

What do I need to do to enable VoLTE on my VoLTE roaming compatible device?

Some devices will default automatically to having the 4G LTE and VoLTE service selected. For other devices you have to enable 4G LTE and VoLTE service in the device settings.

For details on how to check the settings on your device to ensure both 4G LTE and VoLTE service are turned on, visit your device manufacturer’s support pages.

Based on my device type, what services are impacted by the discontinuation of the U.S. 3G network services when I am travelling in the U.S.?

How can I tell if I have a 3G/HSPA only device or a 4G LTE device that supports VoLTE?

There are a number of ways to determine what network standards your mobile device supports.

  1. In your device settings look for your mobile network connection details. Depending on your device and the applicable operating system, you should be able to see a list of which type of network connections your device supports.
  2. You can check the specifications for your device on your device manufacturer’s website or device documentation to determine what network connections it supports and whether it also supports VoLTE.
  3. There are third party websites, such as (see Phone Finder tab), where you can check what network standards are supported by your mobile device.
  4. If in doubt, you should consult the support pages of your service providers’ website or contact your service provider.

How can I determine if my device will still work on the AT&T and T-Mobile networks after they discontinue 3G/HSPA network service?

Question 7 above provides a general overview of what services are impacted based on your device type. If you still have questions, you should contact your service provider directly to determine if your device will continue to work on the AT&T and T-Mobile networks after they discontinue 3G/HSPA services.

What should I do if my phone will no longer work on the AT&T and T-Mobile networks following their discontinuation of 3G / HSPA network services?

If you wish to use mobile voice and data services while travelling in the U.S. you will need to upgrade your device to one that is Voice over LTE (VoLTE) roaming compatible. Contact your service provider to learn more about what upgrade options are available to you.

Compatible 4G LTE devices (without Voice over LTE roaming capabilities) will continue to be able to use data services (but not voice call services) when in the 4G LTE network coverage on AT&T and T-Mobile.

I have a 5G phone, will it continue to work on AT&T and T-Mobile networks?

Yes, 5G phones will be able to work on AT&T and T-Mobile 4G/LTE and compatible 5G networks. If in doubt, you can check the specifications for your device on the device manufacturer’s website.

If my device will no longer work on the AT&T and T-Mobile networks, can I still use my mobile device connected to Wi-Fi when travelling in the U.S.?

The AT&T and T-Mobile 3G/HSPA network service discontinuation should not impact your ability to use your device’s Wi-Fi capabilities when connected to a Wi-Fi network.

Where can I find more information about how the U.S. 3G/HSPA network shutdown will impact me?
