Why is VoLTE important?

Our current 3G network relies on older technology and will start to disappear to make room for more advanced networks.


We’ve been preparing our evolved network for a while to make sure we can continue offering quality mobile services. We are working hard to make sure the transition is as smooth as possible for our members.

  1. What is VoLTE

    VoLTE stands for Voice over LTE network, which basically means a phone call will use the LTE network.  

    But what’s LTE you ask?  

    Great question. LTE stands for Long Term Evolution. It’s basically an evolution of the norms for mobile services.  

  1. The advantages of VoLTE

    Using a VoLTE compatible SIM card with your Fizz mobile plan means you'll be ahead of the game and ready for VoLTE when it becomes available on Fizz's network.  


    You’re already using our ultrafast and vast LTE network when you use data with your mobile plan. The opportunity to use the LTE network for your calls means:   

    • Improved sound quality for your calls.   
    • Faster routing of your calls, meaning the delay for the phone to ring at the other end will be shorter. 

  1. Your VoLTE compatible SIM card

    Your SIM card connects your phone to the Fizz network now 3G and going to LTE. A VoLTE compatible SIM card is therefore required to stay ahead of the game. This SIM card shows a red lightning bolt icon. 



    For the mobile members who currently have a SIM card without a red lightning bolt, Fizz will make sure that each of them gets a FREE VoLTE compatible SIM card.  

    • Each of these members will receive an invitation to order their free SIM card. This process will take place over several months, so don’t worry if you’re not part of the first batch. 
    • Once ordered, your new SIM card will arrive by regular mail, along with the instructions to associate it with your Fizz mobile plan. Changing your SIM card for a VoLTE compatible one will not impact your plan or phone number. 
    • Good to know: To see the confirmation of your SIM card order, go under My parameters > Transaction history > All transactions.


    Changing your SIM card for a VoLTE compatible one will not impact your plan or phone number.

    How to make a SIM card change 


  1. The LTE function on your phone

    Once your new VoLTE compatible SIM card is associated and activated with your Fizz plan, you’ll need to prepare your phone.


    1. Check whether your phone is VoLTE certified on the Fizz network.

    Some already are, others will be soon.

    See the list

    2. Install the manufacturer software update

    Each manufacturer is managing their software rollout so their phone models are compatible with VoLTE. Manufacturers will be making a gradual rollout throughout the year.

    Important: The delay to complete steps 1 and 2 will vary based on the model of your phone. Only when these steps are completed will you be able to go to step 3.

    3. Activate the VoLTE function

    In general, you must go under:

    • Android:

    Calls > (Three little dots) > Call settings

    • Apple:

    General > Cellular network > VoLTE

    The phone uses the VoLTE when during a call the phone continues to display “LTE” in the right corner of the screen. You may need to restart it.

  1. VoLTE coverage

    You’re already enjoying our LTE network when it comes to your mobile data. That network is faster and larger than the 3G network. A VoLTE compatible and certified phone, activated with a VoLTE compatible SIM card will together allow your calls to also use the LTE network instead of the 3G network which is bound to disappear in the near future.

    See the LTE coverage map 

    If you’re travelling in the country, you’ll be roaming using our partner’s LTE network.

    If you are traveling in the United States, including Puerto Rico and the U.S. Virgin Islands, be advised that as of July 2022, only the LTE network is available.

  1. VoLTE and call forwarding

    Once a plan is activated with a VoLTE compatible SIM card, manually setting up call forwarding will not work. Call forwarding for the voicemail option remains functional.

    This is temporary. When Fizz will transition to VoLTE, this situation will be resolved and call forwarding will work when you use a VoLTE compatible phone, activated with a VoLTE compatible SIM card.
