Who will push my Oreo.

I have an unlocked Verizon phone on the koodo network. How and who will give me oreo on my s7

It depends.

As I understand it, the update package will come from Samsung but whether or not you get it would be up to Verizon.

I've seen the case before where a phone won't get an update if that carrier's SIM isn't being used.

So looks like sideloading is my only option
