Each cellular provider in Canada uses its own set of frequencies. Each device supports a different set of frequencies that determine what networks it can connect to. In order for the device to work on certain providers, it must have the proper frequencies. To determine this you can use a website like GSM Arena to determine what frequencies your device supports. This is helpful when unlocking a device to use on a different Canadian provider, or traveling abroad.
Below you will find a tool that will tell you the frequencies each Canadian provider supports. Some devices may be modified to work on different providers as well. You can contact us for more information.
