I have a boost Lg K3 oh (LS450).
I want to link it to my Dz9-007 smart watch.
Do I need an activated micro boost / sprint sim card?
This is the Boost Mobile Australia Community. As Boost Mobile Australia is Pre Paid service provider, I believe you are looking for assistance from Boost Mobile USA.
You can get in contact with Boost Mobile USA or visit their Community Forum for assistance.
However if I have misunderstood and you require assistance with your Boost Mobile Australia Service, you can contact Boost on 125 8881 (8am-9pm, 7 days) or on live chat (24hrs, 7 days)
I'm also curious as to what is needed, after I have bought a smart watch? (I'm waiting for mine to be delivered)
Can I do all of the ordering of the sim & then setup online, rather than ringing the number.
