Internet on your mobile

Understanding what influences mobile data usage

What is data allowance?
Your data allowance is determined by your plan. Beyond this limit, you can continue to make use of the mobile data network, however you will be charged additional fees.

Internet data usage is measured in kilobytes (KB), megabytes (MB) or gigabytes (GB).

A gigabyte (GB) is equal to 1,024 megabytes (MB). A megabyte (MB) is equal to 1,024 kilobytes (KB). Depending on the quantity or volume of data, we will use one or the other of these units of measure.

For example, if you download a song, this represents 10 MB of data usage. If you stream a one-hour show, this represents 500 MB of data usage.

How is my data usage totalled?
Your mobile data usage is influenced by:

  • the way in which you use the mobile network
  • how often you use it
  • the mobile network available at the time of use (Videotron network, national and international partner networks).

Here are examples how various types of use impct mobile data usage:

  • Emailing
    • Emails without attachments are about 10 KB each
    • All email messages that you view or send over the mobile network on your mobile device will count as mobile data usage.
  • File downloads
    • Many types of documents can be viewed or sent over the mobile network. For example (but not limited to): texts, spreadsheets or presentations; photos, music and videos; executable files, etc.
    • Files downloaded via the mobile network to your mobile device will count as mobile data usage.
    • Given the wide variety of file types, it is difficult to assess the amount of mobile data usage these represent.
    • Such files may be downloaded in various ways: either as email attachments or via websites or apps.
  • Surfing the Web
    • Surfing consist of browsing Web pages using a Web browser (e.g. Internet Explorer, Google Chrome, Mozilla Firefox) or browsing information (e.g. social media, news, entertainment, etc.) taken from the Web using various types of applications.
    • The more Internet pages you browse on your device when it’s connected to the wireless network, the more your mobile data usage increases.
    • The more there is multimedia content (images, animations, videos, etc.) on pages viewed, the more your mobile data usage will go up.
    • When pages viewed using a smartphone or tablet via the mobile network are mobile-optimized, data usage will be less significant.
    • A Web page without multimedia content can take upapproximately 100 KB. A Web page with a large quantity of multimedia (e.g. the home page of a news site) can take up approximately 1 MB.
  • Music and/or online radio
    • Downloading music, or listening to/ streaming music and/or radio counts as data usage.
    • One minute of streaming music or radio represent approximately 1 MB. Music or blog downloads represent approximately 2 MB per minute.
  • Watching videos
    • You can stream videos online or download them.
    • There are a multitude of video content providers. E.g. websites, content broadcasters (illico, YouTube, Dailymotion, etc.) and various content delivery applications (Netflix,, etc.)
    • One minute of low quality streaming or downloaded video represents approximately 1 MB. One minute of HD content represents 5 MB or more.
  • Using GPS functionality
    • Barring a manufacturer's note to the contrary, using a smart phone GPS can increase mobile data usage.
    • Using a GPS for directions represents approximately 5 MB/hour.
  • Updating applications
    • Smartphones and tablets feature applications. Applications are regularly updated as software features are added and bugs are fixed.
    • Updates downloaded via the mobile network count as data usage.
  • Online gaming
    • The more the online game has a good picture quality and features real-time (or near real-time) play, the more your mobile data usage will increase.

1024 Kb = 1 Mb et 1024 Mb = 1 Gb
The amount of data you used is written in kilobytes on your invoice. Move the decimal point three places to the left to convert the amount to megabytes, and again three places to the left to convert it to gigabytes (5,500,000 KB is equal to 5,500 MB, or 5.5 GB).
