Link Pixel watch with different phone number under the same family plan

Hi, 

As part of the black Friday deal I got 4 lines and 2 pixel watches. When I check my Telus app, I found one of the watch has been linked with the wrong number in my family account. 

I am wondering if I will need to contact Telus to make the switch to link this Telus watch with the correct but different number that is also under my family account. BTW,  the watch is still on the way to my house, and I haven't activate the watch yet.

Thank you.
