I can see that a sticker is placed in the device that says what you have mentioned but according to Huawei Canada they confirmed that every device they have shipped contain a case even though they check detailed on my IMEI number and confirm that they ship clear case with my device but looks like it gets disappeared from the box. Check out every video over the internet and you will see that is included for each p10 plus.
Even in the video there is no Stricker of what is included but looks like they stick it afterwards after removing case from the box.
Very disappointed and hope Rogers will figure out what exactly happened!
As I have confirmed from Huawei that my IMEI does ship out with protective case.
