How reliable is the VOLTE test (dialling #TEST)?

Hi, I swapped to the VOLTE sim a while ago for my Google Pixel 4a and thought I was all set for the 3G withdrawal. But when I dialed #TEST, it said that the test failed. Looking online, however, it seems like the Pixel 4a is VOLTE compatible, so I'm wondering if others got a false negative too?

    Not completely a Fizz problem. A bit more complicated. :-)

    From the FAQ:  https://fizz.ca/en/faq/compatible-devices#3

    “Now, the question on everyone’s lips, why are certain phones VoLTE certified for some Canadian operators, but not for others?   

    A mobile phone’s VoLTE certification is the result of a technical and commercial agreement between the manufacturer and the operator. Because each operator sets its own requirements and certifications, a given phone may be compatible with VoLTE for one operator, but not for another.

    Here are the reasons why compatibility may differ between operators:  

    • Separate certifications: Each operator must certify the compatibility of a given phone with its own VoLTE network. If an operator has actively participated in this process and requested that the phone be compatible with its VoLTE configuration, the phone will be able to use VoLTE on that operator’s network.   
    • Various VoLTE configurations: Operators may use slightly different technical configurations for their VoLTE service. A phone that is certified with one operator may not be compatible with another operator’s configuration.   
    • Launch date: If an operator launches their VoLTE service and certifies a particular phone, that phone may not be compatible with another operator’s VoLTE if that operator has not yet launched their service or has not yet included that phone in their certification process. 
    • Certification cycle: The certification process of a phone can continue for a few months following its commercial launch. If a device is declared non-compatible with an operator’s VoLTE configuration, it is rare for the manufacturer to modify the phone afterwards to make it compatible.

    Note: If you bring your own phone, and that phone is not on our list of VoLTE-compatible phones, it could still have the VoLTE feature and be able to place calls on the LTE network. Fizz will not, under any circumstances, block or prevent the operation of VoLTE on a phone that hasn’t been certified by the company. If the phone is compatible with the Fizz VoLTE configuration, it will be able to make VoLTE calls. However, we cannot guarantee the proper functioning of that VoLTE service on our network.”

    Cheers,

    Brad
