As Tudor said.... its not VM cable - it is just fake advertising.
When my daughter got some similar rip off cable off Amazon to move her V6 box - she merely succeeded in injecting "noise" into the network and beggering our neighbours connections. Was only discovered when the VM investigating team knocked on our door and asked to see our connections.
They spotted it and changed it to VM cable/connectors and all was well. They also mentioned that she had violated the T&C's and could be chargeable.
Just saying....
