How much is the new tecno phantom 9

I think there may be a misunderstanding here.

Tecno Phantom 9 is not a real device. Tecno is a smartphone brand, and they have released several models, but Phantom 9 is not one of them.

If you're looking for information on the latest Tecno smartphones, I'd be happy to help you with that. Alternatively, if you're interested in a specific model, please let me know the actual name of the device, and I can try to provide you with the latest pricing information.
