iPhones bought from Visible Unlocked

[TLK3]

I am interested in switching to Visible and want to buy either an iPhone 11 or 12 -- but want to know if Visible doesn't work out for me are the iPhones unlocked so I can move the iPhone to another carrier?    Also question number 2 -- if I get the apple care plan through visible can I cancel that plan after a month or two if I decide I don't want it?  

thanks.

So far I know, Visible are selling unlocked phones and you can switch the carriers if you decide it to do. 

For apple care, you can cancel anytime you want.
