Mobile network

A mobile network is a wireless communication system that manages the transmission of voice calls and data between devices and their users. On this page, we will explain how communication via a mobile network works, which networks are available in Canada, and the differences between the various technologies.

What is a mobile network?

In essence, a mobile network consists of three different parts that work together: your device, a base station (often called a cell tower), and a switching centre. When you make a phone call, your mobile phone connects to a nearby base station, which in turn contacts a telephone exchange. The switching centre then connects your number with the person you are calling.

The SIM card you receive when you sign up for a bring your own phone plan, a prepaid plan, or mobile internet determines which network your device can access. The SIM card acts as the link between you and your provider, and contains information about your phone number and the specific services included in your monthly plan or prepaid balance.

Today, many Canadians also use eSIMs, which are digital versions of the physical SIM card built directly into your smartphone, allowing you to activate a plan without a physical card.

Do all providers have their own network?

No, not all providers in Canada own and operate their own physical infrastructure. The Canadian market is built around four major national networks: Rogers, Bell, Telus, and Freedom Mobile (Quebecor).

Smaller providers, often called flanker brands or MVNOs (Mobile Virtual Network Operators), share these networks to provide coverage. Below is a breakdown of which popular providers use which national network:

The differences between 4G and 5G

By 2026, 4G and 5G are the primary standards for mobile communication in Canada. While both allow you to browse the web and stream video, there are significant differences:

• 4G (LTE): This is the reliable workhorse of the Canadian network. It is perfect for everyday tasks like scrolling through social media, checking emails, and streaming standard-definition video.
• 5G and 5G+: These networks offer much faster download speeds and lower latency (less lag). 5G+ uses the 3500 MHz and 3800 MHz spectrum to provide fibre-like speeds wirelessly. It is designed to handle more devices simultaneously, making it ideal for crowded areas like downtown Toronto or Vancouver, and for high-demand activities like cloud gaming or streaming 4K/8K video.

What happened to 2G and 3G?

As of 2026, 2G and 3G networks have been officially decommissioned across Canada. This “sunset” of older technology was necessary to free up radio frequencies for the faster and more efficient 5G networks we use today.

What does the 2G and 3G shutdown mean for me?

Because these networks are no longer active, older devices that rely solely on 2G or 3G technology (including some older “flip phones” and early smartphones) will no longer be able to make calls, send texts, or access data. 

If you have an older device, you must ensure it is VoLTE (Voice over LTE) certified by your provider to stay connected, as standard voice calls now travel over the 4G and 5G data networks.

What to do if you experience network disruptions

1. Check the network status: Most Canadian providers have a “Network Status” or “Outage Map” on their websites. Check there first to see if there are any temporary disruptions or planned maintenance in your neighbourhood.
2. Wait it out: If an outage is confirmed, technicians are likely already working on it. You will simply need to wait until the issue is resolved.
3. Check your device settings: If there are no reported outages, try toggling your Airplane Mode on and off, or restart your device. Ensure your network settings are set to “Automatic.”
4. Contact support: If you’ve tried the steps above and still have no service, it’s time to contact your provider’s customer support for further guidance.
